Given numbers are 647, 129, 900, 190

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 129 are 3 x 43

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 190 are 2 x 5 x 19

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

Given numbers are 647, 129, 900, 190

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

Apply this formula for all numbers.

Step1:

LCM(647, 129) = 83463

GCD(647, 129) = ( 647 x 129 ) / 83463

= 647 / 129

= 647

Step2:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

Step3:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

So, Greatest Common Divisor of 647, 129, 900, 190 is 1
