Given numbers are 709, 420, 492, 451

The list of prime factors of all numbers are

Prime factors of 709 are 709

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 492 are 2 x 2 x 3 x 41

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 709, 420, 492, 451

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

Apply this formula for all numbers.

Step1:

LCM(709, 420) = 297780

GCD(709, 420) = ( 709 x 420 ) / 297780

= 709 / 420

= 709

Step2:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

Step3:

LCM(1, 451) = 451

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

= 1 / 451

= 1

So, Greatest Common Divisor of 709, 420, 492, 451 is 1
