Steps to Calculate GCD of 242, 310, 431, 405 using LCM Formula
Given numbers are 242, 310, 431, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(242, 310) = 37510
GCD(242, 310) = ( 242 x 310 ) / 37510
= 242 / 310
= 242
Step2:
LCM(2, 431) = 862
GCD(2, 431) = ( 2 x 431 ) / 862
= 2 / 431
= 2
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 242, 310, 431, 405 is 1
