Hence, LCM of 400 and 1080 is 10800.

Example: Find lcm of 400 and 1080 by Common Division Method

Hence, LCM of 400 and 1080 is 2 x 2 x 2 x 2 x 3 x 3 x 3 x 5 x 5 = 10800.

Example: Find lcm of 400 and 1080 by Formula

• GCF of 400 and 1080 = 40
• LCM of 400 and 1080 = (400 x 1080) / 40
• => 432000 / 40

Hence, LCM of 400 and 1080 is 10800.
