GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 966) = 136206
GCD(423, 966) = ( 423 x 966 ) / 136206
= 423 / 966
= 423
Step2:
LCM(3, 946) = 2838
GCD(3, 946) = ( 3 x 946 ) / 2838
= 3 / 946
= 3
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 423, 966, 946, 640 is 1
