GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 418) = 91542
GCD(438, 418) = ( 438 x 418 ) / 91542
= 438 / 418
= 438
Step2:
LCM(2, 677) = 1354
GCD(2, 677) = ( 2 x 677 ) / 1354
= 2 / 677
= 2
Step3:
LCM(1, 160) = 160
GCD(1, 160) = ( 1 x 160 ) / 160
= 1 / 160
= 1
So, Greatest Common Divisor of 438, 418, 677, 160 is 1
