Given numbers are 649, 646, 642, 735

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 646 are 2 x 17 x 19

Prime factors of 642 are 2 x 3 x 107

Prime factors of 735 are 3 x 5 x 7 x 7

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

Given numbers are 649, 646, 642, 735

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

Apply this formula for all numbers.

Step1:

LCM(649, 646) = 419254

GCD(649, 646) = ( 649 x 646 ) / 419254

= 649 / 646

= 649

Step2:

LCM(1, 642) = 642

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

= 1 / 642

= 1

Step3:

LCM(1, 735) = 735

GCD(1, 735) = ( 1 x 735 ) / 735

= 1 / 735

= 1

So, Greatest Common Divisor of 649, 646, 642, 735 is 1
