Steps to Calculate GCD of 285, 183, 680, 705 using LCM Formula

Given numbers are 285, 183, 680, 705

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

Apply this formula for all numbers.

Step1:

LCM(285, 183) = 17385

GCD(285, 183) = ( 285 x 183 ) / 17385

= 285 / 183

= 285


Step2:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3


Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1


So, Greatest Common Divisor of 285, 183, 680, 705 is 1
