GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(426, 279) = 39618
GCD(426, 279) = ( 426 x 279 ) / 39618
= 426 / 279
= 426
Step2:
LCM(3, 748) = 2244
GCD(3, 748) = ( 3 x 748 ) / 2244
= 3 / 748
= 3
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 426, 279, 748, 420 is 1
