Steps to Calculate GCD of 618, 642, 58, 395 using LCM Formula
Given numbers are 618, 642, 58, 395
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 642) = 66126
GCD(618, 642) = ( 618 x 642 ) / 66126
= 618 / 642
= 618
Step2:
LCM(6, 58) = 174
GCD(6, 58) = ( 6 x 58 ) / 174
= 6 / 58
= 6
Step3:
LCM(2, 395) = 790
GCD(2, 395) = ( 2 x 395 ) / 790
= 2 / 395
= 2
So, Greatest Common Divisor of 618, 642, 58, 395 is 1
