Steps to Calculate GCD of 17, 80, 85, 68 using LCM Formula

Given numbers are 17, 80, 85, 68

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

Apply this formula for all numbers.

Step1:

LCM(17, 80) = 1360

GCD(17, 80) = ( 17 x 80 ) / 1360

= 17 / 80

= 17


Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1


Step3:

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

= 1 / 68

= 1


So, Greatest Common Divisor of 17, 80, 85, 68 is 1
