Given numbers are 630, 427, 49, 680

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 427 are 7 x 61

Prime factors of 49 are 7 x 7

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 630, 427, 49, 680

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

Apply this formula for all numbers.

Step1:

LCM(630, 427) = 38430

GCD(630, 427) = ( 630 x 427 ) / 38430

= 630 / 427

= 630

Step2:

LCM(7, 49) = 49

GCD(7, 49) = ( 7 x 49 ) / 49

= 7 / 49

= 7

Step3:

LCM(7, 680) = 4760

GCD(7, 680) = ( 7 x 680 ) / 4760

= 7 / 680

= 7

So, Greatest Common Divisor of 630, 427, 49, 680 is 1
