Steps to Calculate GCD of 261, 603, 11, 191 using LCM Formula
Given numbers are 261, 603, 11, 191
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 603) = 17487
GCD(261, 603) = ( 261 x 603 ) / 17487
= 261 / 603
= 261
Step2:
LCM(9, 11) = 99
GCD(9, 11) = ( 9 x 11 ) / 99
= 9 / 11
= 9
Step3:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
So, Greatest Common Divisor of 261, 603, 11, 191 is 1
