Question

find the LCM by Prime method 42 and 11​

Answer 1

Answer:

LCM(11, 42) = 462

Step-by-step explanation:

Prime Factorization of 11 shows:

11 is prime  =>  11^1

Prime Factorization of 42 is:

2 x 3 x 7  =>  2^1 x 3^ x 7^1

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 3, 7, 11

Multiply these factors together to find the LCM.

LCM = 2 x 3 x 7 x 11 = 462

In exponential form:

LCM = 2^1 x 3^1 x 7^1 x 11^1 = 462

LCM = 462

Therefore,

LCM(11, 42) = 462
