Given numbers are 690, 924, 646, 131

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

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

Prime factors of 646 are 2 x 17 x 19

Prime factors of 131 are 131

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

Given numbers are 690, 924, 646, 131

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

Apply this formula for all numbers.

Step1:

LCM(690, 924) = 106260

GCD(690, 924) = ( 690 x 924 ) / 106260

= 690 / 924

= 690

Step2:

LCM(6, 646) = 1938

GCD(6, 646) = ( 6 x 646 ) / 1938

= 6 / 646

= 6

Step3:

LCM(2, 131) = 262

GCD(2, 131) = ( 2 x 131 ) / 262

= 2 / 131

= 2

So, Greatest Common Divisor of 690, 924, 646, 131 is 1
