Steps to Calculate GCD of 249, 687, 587, 991 using LCM Formula
Given numbers are 249, 687, 587, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 687) = 57021
GCD(249, 687) = ( 249 x 687 ) / 57021
= 249 / 687
= 249
Step2:
LCM(3, 587) = 1761
GCD(3, 587) = ( 3 x 587 ) / 1761
= 3 / 587
= 3
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 249, 687, 587, 991 is 1
