GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(178, 668) = 59452
GCD(178, 668) = ( 178 x 668 ) / 59452
= 178 / 668
= 178
Step2:
LCM(2, 828) = 828
GCD(2, 828) = ( 2 x 828 ) / 828
= 2 / 828
= 2
Step3:
LCM(2, 912) = 912
GCD(2, 912) = ( 2 x 912 ) / 912
= 2 / 912
= 2
So, Greatest Common Divisor of 178, 668, 828, 912 is 2
