Given numbers are 635, 159, 407, 642

The list of prime factors of all numbers are

Prime factors of 635 are 5 x 127

Prime factors of 159 are 3 x 53

Prime factors of 407 are 11 x 37

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 635, 159, 407, 642

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

Apply this formula for all numbers.

Step1:

LCM(635, 159) = 100965

GCD(635, 159) = ( 635 x 159 ) / 100965

= 635 / 159

= 635

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 635, 159, 407, 642 is 1
