It is represented as GCF (15, 81).</p> props: <li>The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.</li><li>GCF of two consecutive numbers is always 1.</li><li>Given two numbers 15 and 81, such that GCF is 3 where 3 will always be less than 15 and 81.</li><li>Product of two numbers is always equal to the product of their GCF and LCM.</li> factorsdef: <h4 class="mt-3 heading">What are factors?</h4><p>In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.</p> factorsprops: <li>Every number is a factor of zero (0), since 15 x 0 = 0 and 81 x 0 = 0.</li><li>Every number other than 1 has at least two factors, namely the number itself and 1.</li><li>Every factor of a number is an exact divisor of that number, example 1, 3, 5, 15 are exact divisors of 15 and 1, 3, 9, 27, 81 are exact divisors of 81.</li><li>Factors of 15 are 1, 3, 5, 15. Each factor divides 15 without leaving a remainder.
Simlarly, factors of 81 are 1, 3, 9, 27, 81. Each factor divides 81 without leaving a remainder.</li> examples: <div class="example-box">What is the relation between LCM and GCF (Greatest Common Factor)?<p>GCF and LCM of two numbers can be related as GCF(15, 81) = ( 15 * 81 ) / LCM(15, 81) = 3. </p></div><div class="example-box">What is the GCF of 15 and 81?<p>GCF of 15 and 81 is 3.</p></div><div class="example-box">Ram has 15 cans of Pepsi and 81 cans of Coca Cola. He wants to create identical refreshment tables that will be organized in his house warming party. He also doesn’t want to have any can left over. What is the greatest number of tables that Ram can arrange?<p>To find the greatest number of tables that Ram can stock we need to find the GCF of 15 and 81. Hence GCF of 15 and 81 is 3. So the number of tables that can be arranged is 3.</p></div><div class="example-box">Rubel is creating individual servings of starters for her birthday party. He has 15 pizzas and 81 hamburgers. He wants each serving to be identical, with no left overs. Can you help Rubel in arranging the same in greatest possible way?<p>The greatest number of servings Rubel can create would be equal to the GCF of 15 and 81. Thus GCF of 15 and 81 is 3.</p></div><div class="example-box">Ariel is making ready to eat meals to share with friends. She has 15 bottles of water and 81 cans of food, which she would like to distribute equally, with no left overs. What is the greatest number of boxes Ariel can make?<p>The greatest number of boxes Ariel can make would be equal to GCF of 15 and 81. So the GCF of 15 and 81 is 3.</p></div><div class="example-box">Mary has 15 blue buttons and 81 white buttons. She wants to place them in identical groups without any buttons left, in the greatest way possible. Can you help Mary arranging them in groups?<p>Greatest possible way in which Mary can arrange them in groups would be GCF of 15 and 81. Hence, the GCF of 15 and 81 or the greatest arrangement is 3.</p></div><div class="example-box">Kamal is making identical balloon arrangements for a party. He has 15 maroon balloons, and 81 orange balloons. He wants each arrangement tohave the same number of each color. What is the greatest number of arrangements that he can make if every balloon is used?<p>The greatest number of arrangements that he can make if every balloon is used would be equal to GCF of 15 and 81. So the GCF of 15 and 81 is 3.</p></div><div class="example-box">Kunal is making baskets full of nuts and dried fruits. He has 15 bags of nuts and 81 bags of dried fruits.
