Steps to Calculate GCD of 991, 261, 305, 809 using LCM Formula
Given numbers are 991, 261, 305, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 261) = 258651
GCD(991, 261) = ( 991 x 261 ) / 258651
= 991 / 261
= 991
Step2:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 991, 261, 305, 809 is 1
