Steps to Calculate GCD of 170, 395, 817, 538 using LCM Formula
Given numbers are 170, 395, 817, 538
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 395) = 13430
GCD(170, 395) = ( 170 x 395 ) / 13430
= 170 / 395
= 170
Step2:
LCM(5, 817) = 4085
GCD(5, 817) = ( 5 x 817 ) / 4085
= 5 / 817
= 5
Step3:
LCM(1, 538) = 538
GCD(1, 538) = ( 1 x 538 ) / 538
= 1 / 538
= 1
So, Greatest Common Divisor of 170, 395, 817, 538 is 1
