Steps to Calculate GCD of 24, 20, 72, 75 using LCM Formula

Given numbers are 24, 20, 72, 75

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

Apply this formula for all numbers.

Step1:

LCM(24, 20) = 120

GCD(24, 20) = ( 24 x 20 ) / 120

= 24 / 20

= 24


Step2:

LCM(4, 72) = 72

GCD(4, 72) = ( 4 x 72 ) / 72

= 4 / 72

= 4


Step3:

LCM(4, 75) = 300

GCD(4, 75) = ( 4 x 75 ) / 300

= 4 / 75

= 4


So, Greatest Common Divisor of 24, 20, 72, 75 is 1
