LCM of 31 and 40 is 1240
In mathematics, least common multiple which is commonly known as LCM is defined as the smallest non-zero number which is divisible by both given numbers 31 and 40.
Hence, LCM of 31 and 40 is 1240.
| 2 | 31 40 |
| 2 | 31 20 |
| 2 | 31 10 |
| 5 | 31 5 |
| 31 | 31 1 |
| 1 1 |
Hence, LCM of 31 and 40 is 2 x 2 x 2 x 5 x 31 = 1240.
Hence, LCM of 31 and 40 is 1240.
Franky and Joy are running on a circular track. They take 31 and 40 minutes respectively to go round once. We need to find out at what time (minimum) they will run together again. For this we need to find the LCM of 31 and 40.So, LCM of 31 and 40 is 1240.
To find the least height in feet at which the two piles will be at same height we will find LCM of 31 and 40.So, LCM of 31 and 40 is 1240.
To find the least number of textbooks that each company could have printed we need to find the LCM of 31 and 40.So, LCM of 31 and 40 is 1240.
The problem can be solved using LCM, because we are trying to figure out the least time until they excercise together again.So, LCM of 31 and 40 is 1240.
Greatest common factor or gcf of 31 and 40 is GCF(31, 40) x LCM(31, 40) = (31 x 40) / GCF(31, 40) = 1240.
Least common multiple of 31 and 40 is 1240.
