Answer: b = 15

Step-by-step explanation:

$GCD*LCM=Product\ of\ a\ and \ b\\= 3* 30=a*b\\=3*30=6b\\=90=6b\\=15=b$

Answer 2

Given,

a = 6

GCD(a,b) = 3

LCM(a,b) = 30

To Find,

b =?

Solution,

From the relationship between GCD and LCM, we know that

GCD(a,b) * LCM(a,b) = a * b

Putting the values given in the question,

3 * 30 = 6 * b

b * 6 = 90

b = 90 / 6

b = 15

Hence, if GCD (a,b)=3&LCM=(a,b)=30 if a=6 then b is 15.
