GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(854, 434) = 26474
GCD(854, 434) = ( 854 x 434 ) / 26474
= 854 / 434
= 854
Step2:
LCM(14, 392) = 392
GCD(14, 392) = ( 14 x 392 ) / 392
= 14 / 392
= 14
Step3:
LCM(14, 129) = 1806
GCD(14, 129) = ( 14 x 129 ) / 1806
= 14 / 129
= 14
So, Greatest Common Divisor of 854, 434, 392, 129 is 1
