Given numbers are 654, 557, 187, 855

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 557 are 557

Prime factors of 187 are 11 x 17

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 654, 557, 187, 855

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

Apply this formula for all numbers.

Step1:

LCM(654, 557) = 364278

GCD(654, 557) = ( 654 x 557 ) / 364278

= 654 / 557

= 654

Step2:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 654, 557, 187, 855 is 1
