GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 128) = 13952
GCD(436, 128) = ( 436 x 128 ) / 13952
= 436 / 128
= 436
Step2:
LCM(4, 816) = 816
GCD(4, 816) = ( 4 x 816 ) / 816
= 4 / 816
= 4
Step3:
LCM(4, 162) = 324
GCD(4, 162) = ( 4 x 162 ) / 324
= 4 / 162
= 4
So, Greatest Common Divisor of 436, 128, 816, 162 is 2
