### What is HCF and LCM?

The Highest Common Factor (HCF) of two or more given numbers is the largest number which divides each of the given numbers without leaving any remainder. The Lowest Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.

### What is the HCF of 145 and 232?

29
What is HCF of 145 and 232? Answer: HCF of 145 and 232 is 29.

What is the LCM of 117 and 221?

Therefore, the HCF of 117 and 221 is 13 and the LCM of 117 and 221 is 1989.

What is the HCF of 77 and 99?

The GCF of 77 and 99 is 11.

#### What is the LCM of 145?

LCM of 87 and 145 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 31 × 51 × 291 = 435. Hence, the LCM of 87 and 145 by prime factorization is 435.

#### What is the HCF of 12 and 18?

Answer: HCF of 12 and 18 is 6.

What is the example of LCM?

LCM denotes the least common factor or multiple of any two or more given integers. For example, L.C.M of 16 and 20 will be 2 x 2 x 2 x 2 x 5 = 80, where 80 is the smallest common multiple for numbers 16 and 20. Now, if we consider the multiples of 16 and 20, we get; 16 → 16, 32, 48, 64, 80,…

What is the HCF of 145?

To find the HCF of 145 and 232, we will find the prime factorization of the given numbers, i.e. 145 = 5 × 29; 232 = 2 × 2 × 2 × 29. ⇒ Since 29 is the only common prime factor of 145 and 232. Hence, HCF (145, 232) = 29.
