Given numbers are 687, 653, 156, 703

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

Apply this formula for all numbers.

Step1:

LCM(687, 653) = 448611

GCD(687, 653) = ( 687 x 653 ) / 448611

= 687 / 653

= 687

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

Step3:

LCM(1, 703) = 703

GCD(1, 703) = ( 1 x 703 ) / 703

= 1 / 703

= 1

So, Greatest Common Divisor of 687, 653, 156, 703 is 1
