Given numbers are 686, 651, 240, 550

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 651 are 3 x 7 x 31

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 686, 651, 240, 550

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

Apply this formula for all numbers.

Step1:

LCM(686, 651) = 63798

GCD(686, 651) = ( 686 x 651 ) / 63798

= 686 / 651

= 686

Step2:

LCM(7, 240) = 1680

GCD(7, 240) = ( 7 x 240 ) / 1680

= 7 / 240

= 7

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 686, 651, 240, 550 is 1
