Given numbers are 457, 770, 865, 630

The list of prime factors of all numbers are

Prime factors of 457 are 457

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 865 are 5 x 173

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 457, 770, 865, 630

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

Apply this formula for all numbers.

Step1:

LCM(457, 770) = 351890

GCD(457, 770) = ( 457 x 770 ) / 351890

= 457 / 770

= 457

Step2:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 457, 770, 865, 630 is 1
