Steps to Calculate GCD of 70, 75, 24, 90 using LCM Formula
Given numbers are 70, 75, 24, 90
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(70, 75) = 1050
GCD(70, 75) = ( 70 x 75 ) / 1050
= 70 / 75
= 70
Step2:
LCM(5, 24) = 120
GCD(5, 24) = ( 5 x 24 ) / 120
= 5 / 24
= 5
Step3:
LCM(1, 90) = 90
GCD(1, 90) = ( 1 x 90 ) / 90
= 1 / 90
= 1
So, Greatest Common Divisor of 70, 75, 24, 90 is 1
