Given numbers are 685, 462, 272, 451

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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 685, 462, 272, 451

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

Apply this formula for all numbers.

Step1:

LCM(685, 462) = 316470

GCD(685, 462) = ( 685 x 462 ) / 316470

= 685 / 462

= 685

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 451) = 451

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

= 1 / 451

= 1

So, Greatest Common Divisor of 685, 462, 272, 451 is 1
