Given numbers are 142, 808, 389, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 808) = 57368
GCD(142, 808) = ( 142 x 808 ) / 57368
= 142 / 808
= 142
Step2:
LCM(2, 389) = 778
GCD(2, 389) = ( 2 x 389 ) / 778
= 2 / 389
= 2
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 142, 808, 389, 321 is 1
