Steps to Calculate GCD of 305, 415, 698, 556 using LCM Formula
Given numbers are 305, 415, 698, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 415) = 25315
GCD(305, 415) = ( 305 x 415 ) / 25315
= 305 / 415
= 305
Step2:
LCM(5, 698) = 3490
GCD(5, 698) = ( 5 x 698 ) / 3490
= 5 / 698
= 5
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 305, 415, 698, 556 is 1
