Given numbers are 683, 637, 840, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(683, 637) = 435071
GCD(683, 637) = ( 683 x 637 ) / 435071
= 683 / 637
= 683
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 683, 637, 840, 631 is 1
