Steps to Calculate GCD of 28, 25, 25, 17 using LCM Formula
Given numbers are 28, 25, 25, 17
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(28, 25) = 700
GCD(28, 25) = ( 28 x 25 ) / 700
= 28 / 25
= 28
Step2:
LCM(1, 25) = 25
GCD(1, 25) = ( 1 x 25 ) / 25
= 1 / 25
= 1
Step3:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
So, Greatest Common Divisor of 28, 25, 25, 17 is 1
