Given numbers are 620, 287, 70, 459

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 287 are 7 x 41

Prime factors of 70 are 2 x 5 x 7

Prime factors of 459 are 3 x 3 x 3 x 17

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

Given numbers are 620, 287, 70, 459

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

Apply this formula for all numbers.

Step1:

LCM(620, 287) = 177940

GCD(620, 287) = ( 620 x 287 ) / 177940

= 620 / 287

= 620

Step2:

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

= 1 / 70

= 1

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 620, 287, 70, 459 is 1
