Given numbers are 687, 744, 109, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 744) = 170376
GCD(687, 744) = ( 687 x 744 ) / 170376
= 687 / 744
= 687
Step2:
LCM(3, 109) = 327
GCD(3, 109) = ( 3 x 109 ) / 327
= 3 / 109
= 3
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 687, 744, 109, 631 is 1
