Given numbers are 642, 273, 766, 657

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 273 are 3 x 7 x 13

Prime factors of 766 are 2 x 383

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 642, 273, 766, 657

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

Apply this formula for all numbers.

Step1:

LCM(642, 273) = 58422

GCD(642, 273) = ( 642 x 273 ) / 58422

= 642 / 273

= 642

Step2:

LCM(3, 766) = 2298

GCD(3, 766) = ( 3 x 766 ) / 2298

= 3 / 766

= 3

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 642, 273, 766, 657 is 1
