Steps to Calculate GCD of 991, 621, 165, 328 using LCM Formula
Given numbers are 991, 621, 165, 328
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 621) = 615411
GCD(991, 621) = ( 991 x 621 ) / 615411
= 991 / 621
= 991
Step2:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
Step3:
LCM(1, 328) = 328
GCD(1, 328) = ( 1 x 328 ) / 328
= 1 / 328
= 1
So, Greatest Common Divisor of 991, 621, 165, 328 is 1
