Given numbers are 990, 172, 883, 638

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 172 are 2 x 2 x 43

Prime factors of 883 are 883

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 990, 172, 883, 638

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

Apply this formula for all numbers.

Step1:

LCM(990, 172) = 85140

GCD(990, 172) = ( 990 x 172 ) / 85140

= 990 / 172

= 990

Step2:

LCM(2, 883) = 1766

GCD(2, 883) = ( 2 x 883 ) / 1766

= 2 / 883

= 2

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 990, 172, 883, 638 is 1
