Steps to Calculate GCD of 17, 44, 89, 28 using LCM Formula

Given numbers are 17, 44, 89, 28

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(17, 44) = 748

GCD(17, 44) = ( 17 x 44 ) / 748

= 17 / 44

= 17

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

= 1 / 89

= 1


Step3:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1


So, Greatest Common Divisor of 17, 44, 89, 28 is 1
