Steps to Calculate GCD of 285, 707, 809, 389 using LCM Formula
Given numbers are 285, 707, 809, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 707) = 201495
GCD(285, 707) = ( 285 x 707 ) / 201495
= 285 / 707
= 285
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
So, Greatest Common Divisor of 285, 707, 809, 389 is 1
