Given numbers are 489, 520, 651, 700

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 651 are 3 x 7 x 31

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

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

Given numbers are 489, 520, 651, 700

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

Apply this formula for all numbers.

Step1:

LCM(489, 520) = 254280

GCD(489, 520) = ( 489 x 520 ) / 254280

= 489 / 520

= 489

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

Step3:

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

= 1 / 700

= 1

So, Greatest Common Divisor of 489, 520, 651, 700 is 1
