Steps to Calculate GCD of 689, 687, 55, 593 using LCM Formula
Given numbers are 689, 687, 55, 593
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 687) = 473343
GCD(689, 687) = ( 689 x 687 ) / 473343
= 689 / 687
= 689
Step2:
LCM(1, 55) = 55
GCD(1, 55) = ( 1 x 55 ) / 55
= 1 / 55
= 1
Step3:
LCM(1, 593) = 593
GCD(1, 593) = ( 1 x 593 ) / 593
= 1 / 593
= 1
So, Greatest Common Divisor of 689, 687, 55, 593 is 1
