Given numbers are 358, 364, 642, 649

The list of prime factors of all numbers are

Prime factors of 358 are 2 x 179

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 642 are 2 x 3 x 107

Prime factors of 649 are 11 x 59

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

Given numbers are 358, 364, 642, 649

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

Apply this formula for all numbers.

Step1:

LCM(358, 364) = 65156

GCD(358, 364) = ( 358 x 364 ) / 65156

= 358 / 364

= 358

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 649) = 1298

GCD(2, 649) = ( 2 x 649 ) / 1298

= 2 / 649

= 2

So, Greatest Common Divisor of 358, 364, 642, 649 is 1
