GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 678) = 155262
GCD(687, 678) = ( 687 x 678 ) / 155262
= 687 / 678
= 687
Step2:
LCM(3, 969) = 969
GCD(3, 969) = ( 3 x 969 ) / 969
= 3 / 969
= 3
Step3:
LCM(3, 676) = 2028
GCD(3, 676) = ( 3 x 676 ) / 2028
= 3 / 676
= 3
So, Greatest Common Divisor of 687, 678, 969, 676 is 1
