GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 102) = 32028
GCD(628, 102) = ( 628 x 102 ) / 32028
= 628 / 102
= 628
Step2:
LCM(2, 220) = 220
GCD(2, 220) = ( 2 x 220 ) / 220
= 2 / 220
= 2
Step3:
LCM(2, 789) = 1578
GCD(2, 789) = ( 2 x 789 ) / 1578
= 2 / 789
= 2
So, Greatest Common Divisor of 628, 102, 220, 789 is 1
