Given numbers are 663, 600, 70, 861

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

Prime factors of 70 are 2 x 5 x 7

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 663, 600, 70, 861

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

Apply this formula for all numbers.

Step1:

LCM(663, 600) = 132600

GCD(663, 600) = ( 663 x 600 ) / 132600

= 663 / 600

= 663

Step2:

LCM(3, 70) = 210

GCD(3, 70) = ( 3 x 70 ) / 210

= 3 / 70

= 3

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 663, 600, 70, 861 is 1
