Given numbers are 427, 924, 658, 649

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

Prime factors of 658 are 2 x 7 x 47

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 427, 924, 658, 649

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

Apply this formula for all numbers.

Step1:

LCM(427, 924) = 56364

GCD(427, 924) = ( 427 x 924 ) / 56364

= 427 / 924

= 427

Step2:

LCM(7, 658) = 658

GCD(7, 658) = ( 7 x 658 ) / 658

= 7 / 658

= 7

Step3:

LCM(7, 649) = 4543

GCD(7, 649) = ( 7 x 649 ) / 4543

= 7 / 649

= 7

So, Greatest Common Divisor of 427, 924, 658, 649 is 1
