Steps to Calculate GCD of 169, 343, 431, 355 using LCM Formula
Given numbers are 169, 343, 431, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 343) = 57967
GCD(169, 343) = ( 169 x 343 ) / 57967
= 169 / 343
= 169
Step2:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 169, 343, 431, 355 is 1
