Steps to Calculate GCD of 991, 221, 813, 423 using LCM Formula
Given numbers are 991, 221, 813, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 221) = 219011
GCD(991, 221) = ( 991 x 221 ) / 219011
= 991 / 221
= 991
Step2:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 991, 221, 813, 423 is 1
