Steps to Calculate GCD of 521, 991, 401, 991 using LCM Formula
Given numbers are 521, 991, 401, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 991) = 516311
GCD(521, 991) = ( 521 x 991 ) / 516311
= 521 / 991
= 521
Step2:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 521, 991, 401, 991 is 1
