GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 304) = 97584
GCD(642, 304) = ( 642 x 304 ) / 97584
= 642 / 304
= 642
Step2:
LCM(2, 966) = 966
GCD(2, 966) = ( 2 x 966 ) / 966
= 2 / 966
= 2
Step3:
LCM(2, 196) = 196
GCD(2, 196) = ( 2 x 196 ) / 196
= 2 / 196
= 2
So, Greatest Common Divisor of 642, 304, 966, 196 is 2
