GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 964) = 189908
GCD(394, 964) = ( 394 x 964 ) / 189908
= 394 / 964
= 394
Step2:
LCM(2, 961) = 1922
GCD(2, 961) = ( 2 x 961 ) / 1922
= 2 / 961
= 2
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 394, 964, 961, 390 is 1
