Steps to Calculate GCD of 707, 287, 728, 389 using LCM Formula
Given numbers are 707, 287, 728, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(707, 287) = 28987
GCD(707, 287) = ( 707 x 287 ) / 28987
= 707 / 287
= 707
Step2:
LCM(7, 728) = 728
GCD(7, 728) = ( 7 x 728 ) / 728
= 7 / 728
= 7
Step3:
LCM(7, 389) = 2723
GCD(7, 389) = ( 7 x 389 ) / 2723
= 7 / 389
= 7
So, Greatest Common Divisor of 707, 287, 728, 389 is 1
