GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(854, 642) = 274134
GCD(854, 642) = ( 854 x 642 ) / 274134
= 854 / 642
= 854
Step2:
LCM(2, 399) = 798
GCD(2, 399) = ( 2 x 399 ) / 798
= 2 / 399
= 2
Step3:
LCM(1, 966) = 966
GCD(1, 966) = ( 1 x 966 ) / 966
= 1 / 966
= 1
So, Greatest Common Divisor of 854, 642, 399, 966 is 1
