Given numbers are 990, 434, 15, 572

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 434 are 2 x 7 x 31

Prime factors of 15 are 3 x 5

Prime factors of 572 are 2 x 2 x 11 x 13

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 990, 434, 15, 572

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(990, 434) = 214830

GCD(990, 434) = ( 990 x 434 ) / 214830

= 990 / 434

= 990

Step2:

LCM(2, 15) = 30

GCD(2, 15) = ( 2 x 15 ) / 30

= 2 / 15

= 2

Step3:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

So, Greatest Common Divisor of 990, 434, 15, 572 is 1
