Question

the gcf of two numbers is 3 and their lcm is 180 if one of the number is 45 what is the other number ​

Answer 1

Answer:

Number property:

The product of the two numbers = (GCF)*(LCM)

So if the 2nd number is x

45x = 3(180)

x = 12

check: 12 and 45

12 = 2*2*3

45 = 3*3*5

So the LCF = 3

So the LCM = 2*2*3*3*5 = 180
