GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 964) = 60732
GCD(126, 964) = ( 126 x 964 ) / 60732
= 126 / 964
= 126
Step2:
LCM(2, 394) = 394
GCD(2, 394) = ( 2 x 394 ) / 394
= 2 / 394
= 2
Step3:
LCM(2, 861) = 1722
GCD(2, 861) = ( 2 x 861 ) / 1722
= 2 / 861
= 2
So, Greatest Common Divisor of 126, 964, 394, 861 is 1
