Steps to Calculate GCD of 161, 290, 813, 761 using LCM Formula
Given numbers are 161, 290, 813, 761
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 290) = 46690
GCD(161, 290) = ( 161 x 290 ) / 46690
= 161 / 290
= 161
Step2:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
Step3:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
So, Greatest Common Divisor of 161, 290, 813, 761 is 1
