Steps to Calculate GCD of 161, 340, 289, 505 using LCM Formula

Given numbers are 161, 340, 289, 505

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(161, 340) = 54740

GCD(161, 340) = ( 161 x 340 ) / 54740

= 161 / 340

= 161


Step2:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1


Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1


So, Greatest Common Divisor of 161, 340, 289, 505 is 1
