Steps to Calculate GCD of 121, 553, 251, 663 using LCM Formula
Given numbers are 121, 553, 251, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 553) = 66913
GCD(121, 553) = ( 121 x 553 ) / 66913
= 121 / 553
= 121
Step2:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 121, 553, 251, 663 is 1
