Steps to Calculate GCD of 405, 865, 609, 457 using LCM Formula
Given numbers are 405, 865, 609, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 865) = 70065
GCD(405, 865) = ( 405 x 865 ) / 70065
= 405 / 865
= 405
Step2:
LCM(5, 609) = 3045
GCD(5, 609) = ( 5 x 609 ) / 3045
= 5 / 609
= 5
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 405, 865, 609, 457 is 1
