Que. What is the difference between the lcm and hcf of the number 20 30 and 40?
Solution: Dear viewers in this question we have to do factors of these 20, 30, and 40 numbers.
And then we will find the LCM and HCF of these numbers.
After the LCM and HCF calculation, we will find the difference.
So, Let’s start factors
20 = 2X2X5
HCF (Highest Common factors) of these Numbers is 2X5 = 10.
LCM of these numbers is 2X2X2X3X5 = 120.
So, difference between the LCM and HCF of the number 20 30 and 40 is LCM – HCF = 120 – 10 = 110.
What is the difference between the LCM and HCF of the number 20 30 and 40
I hope you like the answer and our solution method.
