Given numbers are 851, 693, 421, 451

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 421 are 421

Prime factors of 451 are 11 x 41

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

Given numbers are 851, 693, 421, 451

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

Apply this formula for all numbers.

Step1:

LCM(851, 693) = 589743

GCD(851, 693) = ( 851 x 693 ) / 589743

= 851 / 693

= 851

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 851, 693, 421, 451 is 1
