How do you find the product of two numbers when HCF and LCM are given?

For example: Find HCF and LCM of 9 and 12. And verify HCF × LCM = Product of the two numbers. Product of 9 and 12 = 9 x 12 = 108. Hence, HCF(9, 12) × LCM(9, 12) = Product of 9 and 12.

What is the H.C.F of 275 and 525?

25
∴ The HCF obtained by long division method is 25.

What is the relation between H.C.F and H.C.F of two number?

(i) The product of LCM and HCF of the given natural numbers is equivalent to the product of the given numbers. Consider two numbers A and B, then. (ii) The LCM of given co-prime numbers is equal to the product of the numbers since the HCF of co-prime numbers is 1.

Which number should be added to 306 so that it becomes prime?

Answer is “5”

What is the HCF of 105 and 154?

7
Answer: HCF of 105 and 154 is 7.

How do you find the H.C.F of two numbers?

HCF of two numbers by Division Method

1. First, divide the large number by a small number.
2. If the remainder is left, then divide the first divisor by remainder.
3. If the remainder divides the first divisor completely, then it is the HCF or highest common factor of the given two numbers.

How to calculate LCM & HCF?

This how to calculate LCM & HCF :-FACTORIZATION METHOD In the hcf by factorization method,we find the greatest common factor by listing down the factors of the numbers. Step 1: List down the factors of all the given numbers. Step 2: Look for the highest factor among the listed factors which are common for both the given numbers.

What is least common multiple and HCF in math?

Least Common Multiple is also known as Smallest Common Multiple i.e. the smallest positive integer that is divisible by more than one integer. HCF – Highest Common Factor (HCF) of two or more numbers is the greatest number which divides each of them exactly.

What is the difference between LCF and HCF?

HCF – Highest Common Factor (HCF) of two or more numbers is the greatest number which divides each of them exactly. LCF – Least Common Factor is a least number that divide any number and leaves remainder zero. Type 1: Find the greatest or smallest number.

How to find the HCF of 12 and 15 using factors?

HCF can be calculated using: 1. Factoring Example: Find the HCF of 12 and 15 using factors? Step 1: List all of the factors of the given numbers. Step 2: Circle or highlight the numbers that exist in the factors of both numbers and should be the greatest common number.
