GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(419, 946) = 396374
GCD(419, 946) = ( 419 x 946 ) / 396374
= 419 / 946
= 419
Step2:
LCM(1, 812) = 812
GCD(1, 812) = ( 1 x 812 ) / 812
= 1 / 812
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 419, 946, 812, 638 is 1
