Steps to Calculate GCD of 251, 689, 12, 398 using LCM Formula
Given numbers are 251, 689, 12, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 689) = 172939
GCD(251, 689) = ( 251 x 689 ) / 172939
= 251 / 689
= 251
Step2:
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
= 1 / 12
= 1
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 251, 689, 12, 398 is 1
