Given numbers are 642, 783, 635, 767

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 635 are 5 x 127

Prime factors of 767 are 13 x 59

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

Given numbers are 642, 783, 635, 767

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

Apply this formula for all numbers.

Step1:

LCM(642, 783) = 167562

GCD(642, 783) = ( 642 x 783 ) / 167562

= 642 / 783

= 642

Step2:

LCM(3, 635) = 1905

GCD(3, 635) = ( 3 x 635 ) / 1905

= 3 / 635

= 3

Step3:

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

= 1 / 767

= 1

So, Greatest Common Divisor of 642, 783, 635, 767 is 1
