Given numbers are 642, 176, 285, 654

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 176 are 2 x 2 x 2 x 2 x 11

Prime factors of 285 are 3 x 5 x 19

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 642, 176, 285, 654

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

Apply this formula for all numbers.

Step1:

LCM(642, 176) = 56496

GCD(642, 176) = ( 642 x 176 ) / 56496

= 642 / 176

= 642

Step2:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 642, 176, 285, 654 is 1
