Lcm Of 12 And 20

MC of 12.20.35? 3

First, factor each number into its main format:

12 = 2 * 2 * 3

20 = 2 * 2 * 5

35 = 5 * 7

Take the number from the first number: 2 * 2 * 3. If there are other numbers that have these numbers, cross them. You should cross out 2 * 2 in 20 digits and go to the base number of 20. Two 2 have already crossed out, except for No. 5. Add them to your number list (2 * 2 * 3 * 5) and cross. The remaining five numbers (35 in this example). To continue, the first number of 35 has only 7 numbers. Add it to your list of numbers and multiply by your answer:

2 * 2 * 3 * 5 * 7 = 420

LCM is 420.

12 = 2 * 2 * 3 of lcm

20 = 2 * 2 * 5 of lcm

lcm of 35 = 5 * 7

Total Lcm = 2 * 2 * 3 * 5 * 7 = 420
