Given numbers are 946, 643, 139, 446
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(946, 643) = 608278
GCD(946, 643) = ( 946 x 643 ) / 608278
= 946 / 643
= 946
Step2:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
Step3:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
So, Greatest Common Divisor of 946, 643, 139, 446 is 1
