Steps to Calculate GCD of 817, 403, 193, 428 using LCM Formula
Given numbers are 817, 403, 193, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(817, 403) = 329251
GCD(817, 403) = ( 817 x 403 ) / 329251
= 817 / 403
= 817
Step2:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 817, 403, 193, 428 is 1
