Given numbers are 747, 640, 851, 455

The list of prime factors of all numbers are

Prime factors of 747 are 3 x 3 x 83

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 851 are 23 x 37

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 747, 640, 851, 455

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

Apply this formula for all numbers.

Step1:

LCM(747, 640) = 478080

GCD(747, 640) = ( 747 x 640 ) / 478080

= 747 / 640

= 747

Step2:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 747, 640, 851, 455 is 1
