Given numbers are 687, 262, 660, 814

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 262 are 2 x 131

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 814 are 2 x 11 x 37

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

Given numbers are 687, 262, 660, 814

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

Apply this formula for all numbers.

Step1:

LCM(687, 262) = 179994

GCD(687, 262) = ( 687 x 262 ) / 179994

= 687 / 262

= 687

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

So, Greatest Common Divisor of 687, 262, 660, 814 is 1
