GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(676, 246) = 83148
GCD(676, 246) = ( 676 x 246 ) / 83148
= 676 / 246
= 676
Step2:
LCM(2, 806) = 806
GCD(2, 806) = ( 2 x 806 ) / 806
= 2 / 806
= 2
Step3:
LCM(2, 420) = 420
GCD(2, 420) = ( 2 x 420 ) / 420
= 2 / 420
= 2
So, Greatest Common Divisor of 676, 246, 806, 420 is 2
