Answer 1

Answer:

Ans 1.) A number or quantity that when multiplied with another produces a given number or expression.

Step-by-step explanation:

Ans 2) . defines the greatest factor present in between given two or more numbers, whereas L.C.M. ... defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.

Ans 3.) A prime number is a number which has exactly two factors i.e. '1' and number itself. A composite number has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number.

Answer 2

Q. no. 1: The Number obtain by multiplying any two or more no.s are called factor..

Q. no. 2: * The least or smallest common multiple of any two or more given natural numbers are termed as LCM. For example, LCM of 10, 15, and 20 is 60.

* The largest or greatest factor common to any two or more given natural numbers is termed as HCF. For example, HCF of 4, 6 and 8 is 2.

Q. no. 3. * A prime number is a number which has exactly two factors i.e. '1' and number itself.

* A composite number has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number.
