Steps to Calculate GCD of 821, 898, 550, 251 using LCM Formula
Given numbers are 821, 898, 550, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 898) = 737258
GCD(821, 898) = ( 821 x 898 ) / 737258
= 821 / 898
= 821
Step2:
LCM(1, 550) = 550
GCD(1, 550) = ( 1 x 550 ) / 550
= 1 / 550
= 1
Step3:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
So, Greatest Common Divisor of 821, 898, 550, 251 is 1
