Given numbers are 401, 894, 780, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 894) = 358494
GCD(401, 894) = ( 401 x 894 ) / 358494
= 401 / 894
= 401
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 401, 894, 780, 423 is 1
