Steps to Calculate GCD of 121, 670, 81, 481 using LCM Formula
Given numbers are 121, 670, 81, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 670) = 81070
GCD(121, 670) = ( 121 x 670 ) / 81070
= 121 / 670
= 121
Step2:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
Step3:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
So, Greatest Common Divisor of 121, 670, 81, 481 is 1
