Given numbers are 650, 642, 163, 655

The list of prime factors of all numbers are

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 642 are 2 x 3 x 107

Prime factors of 163 are 163

Prime factors of 655 are 5 x 131

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

Given numbers are 650, 642, 163, 655

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

Apply this formula for all numbers.

Step1:

LCM(650, 642) = 208650

GCD(650, 642) = ( 650 x 642 ) / 208650

= 650 / 642

= 650

Step2:

LCM(2, 163) = 326

GCD(2, 163) = ( 2 x 163 ) / 326

= 2 / 163

= 2

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 650, 642, 163, 655 is 1
