GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(745, 968) = 721160
GCD(745, 968) = ( 745 x 968 ) / 721160
= 745 / 968
= 745
Step2:
LCM(1, 954) = 954
GCD(1, 954) = ( 1 x 954 ) / 954
= 1 / 954
= 1
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 745, 968, 954, 421 is 1
