GCD of numbers is the greatest common divisor

So, the GCD (630, 840, 651, 953) = 1.

Given numbers are 630, 840, 651, 953

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 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 651 are 3 x 7 x 31

Prime factors of 953 are 953

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

Given numbers are 630, 840, 651, 953

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

Apply this formula for all numbers.

Step1:

LCM(630, 840) = 2520

GCD(630, 840) = ( 630 x 840 ) / 2520

= 630 / 840

= 630

Step2:

LCM(210, 651) = 6510

GCD(210, 651) = ( 210 x 651 ) / 6510

= 210 / 651

= 210

Step3:

LCM(21, 953) = 20013

GCD(21, 953) = ( 21 x 953 ) / 20013

= 21 / 953

= 21

So, Greatest Common Divisor of 630, 840, 651, 953 is 1
