None of those numbers share any common factors with each other, so the answer is just 5*6*7 = 210.

There are no factors common to all three numbers 5, 6 and 7. Hence their LCM would be the product of the numbers which is 5*6*7=210.

Since all of the numbers and their composite prime factors are relatively prime, the lcm is the product of the the 3 numbers or 210.

What u have to do is find the prime factorization of the 3 numbers.
5: 5(already prime)
7: 7(already prime)
6: 2x3
Then u multiple them all since you have no matching numbers.
5x7x2x3=210
