Steps to Calculate GCD of 445, 323, 605, 991 using LCM Formula
Given numbers are 445, 323, 605, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 323) = 143735
GCD(445, 323) = ( 445 x 323 ) / 143735
= 445 / 323
= 445
Step2:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 445, 323, 605, 991 is 1
