Given numbers are 655, 391, 430, 924

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 391 are 17 x 23

Prime factors of 430 are 2 x 5 x 43

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

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

Given numbers are 655, 391, 430, 924

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

Apply this formula for all numbers.

Step1:

LCM(655, 391) = 256105

GCD(655, 391) = ( 655 x 391 ) / 256105

= 655 / 391

= 655

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

Step3:

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

= 1 / 924

= 1

So, Greatest Common Divisor of 655, 391, 430, 924 is 1
