Hector Kirby · Answer 1

D) 2² * 3² * 5 * 7

Step-by-step explanation:

dа ta:

Factors of first number = 2² * 3 * 5

Factors of second number = 2 * 3² * 2 * 7

Calculations:

Rewrite the factors in ascending order

Factors of first number = 2² * 3 * 5

Factors of second number = 2² * 3² * 7

Multiply each factor by the greatest number of times it occurs in either number

LCM = 2² * 3² * 5 * 7
