GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 772) = 530364
GCD(687, 772) = ( 687 x 772 ) / 530364
= 687 / 772
= 687
Step2:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
Step3:
LCM(1, 896) = 896
GCD(1, 896) = ( 1 x 896 ) / 896
= 1 / 896
= 1
So, Greatest Common Divisor of 687, 772, 669, 896 is 1
