Given numbers are 630, 785, 851, 393

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 785 are 5 x 157

Prime factors of 851 are 23 x 37

Prime factors of 393 are 3 x 131

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

Given numbers are 630, 785, 851, 393

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

Apply this formula for all numbers.

Step1:

LCM(630, 785) = 98910

GCD(630, 785) = ( 630 x 785 ) / 98910

= 630 / 785

= 630

Step2:

LCM(5, 851) = 4255

GCD(5, 851) = ( 5 x 851 ) / 4255

= 5 / 851

= 5

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 630, 785, 851, 393 is 1
