Steps to Calculate GCD of 385, 658, 502, 398 using LCM Formula
Given numbers are 385, 658, 502, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 658) = 36190
GCD(385, 658) = ( 385 x 658 ) / 36190
= 385 / 658
= 385
Step2:
LCM(7, 502) = 3514
GCD(7, 502) = ( 7 x 502 ) / 3514
= 7 / 502
= 7
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 385, 658, 502, 398 is 1
