Steps to Calculate GCD of 398, 618, 125, 946 using LCM Formula
Given numbers are 398, 618, 125, 946
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 618) = 122982
GCD(398, 618) = ( 398 x 618 ) / 122982
= 398 / 618
= 398
Step2:
LCM(2, 125) = 250
GCD(2, 125) = ( 2 x 125 ) / 250
= 2 / 125
= 2
Step3:
LCM(1, 946) = 946
GCD(1, 946) = ( 1 x 946 ) / 946
= 1 / 946
= 1
So, Greatest Common Divisor of 398, 618, 125, 946 is 1
