Given numbers are 945, 830, 921, 630

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 830 are 2 x 5 x 83

Prime factors of 921 are 3 x 307

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

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

Given numbers are 945, 830, 921, 630

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

Apply this formula for all numbers.

Step1:

LCM(945, 830) = 156870

GCD(945, 830) = ( 945 x 830 ) / 156870

= 945 / 830

= 945

Step2:

LCM(5, 921) = 4605

GCD(5, 921) = ( 5 x 921 ) / 4605

= 5 / 921

= 5

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 945, 830, 921, 630 is 1
