Steps to Calculate GCD of 705, 641, 609, 906 using LCM Formula
Given numbers are 705, 641, 609, 906
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 641) = 451905
GCD(705, 641) = ( 705 x 641 ) / 451905
= 705 / 641
= 705
Step2:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
Step3:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
So, Greatest Common Divisor of 705, 641, 609, 906 is 1
