Given numbers are 647, 858, 638, 600

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 638 are 2 x 11 x 29

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

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

Given numbers are 647, 858, 638, 600

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

Apply this formula for all numbers.

Step1:

LCM(647, 858) = 555126

GCD(647, 858) = ( 647 x 858 ) / 555126

= 647 / 858

= 647

Step2:

LCM(1, 638) = 638

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

= 1 / 638

= 1

Step3:

LCM(1, 600) = 600

GCD(1, 600) = ( 1 x 600 ) / 600

= 1 / 600

= 1

So, Greatest Common Divisor of 647, 858, 638, 600 is 1
