Steps to Calculate GCD of 478, 147, 321, 664 using LCM Formula

Given numbers are 478, 147, 321, 664

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(478, 147) = 70266

GCD(478, 147) = ( 478 x 147 ) / 70266

= 478 / 147

= 478


Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1


Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1


So, Greatest Common Divisor of 478, 147, 321, 664 is 1
