Question

(2)Find the HCF and LCM of 145,232​

Answer 1

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

145 = 5 × 29;

145 is not a prime, is a composite number;

232 = 23 × 29;

232 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

Calculate the least common multiple, lcm:

Multiply all the prime factors, by the largest exponents (if any).

lcm (145; 232) = 23 × 5 × 29;

lcm (145; 232) = 23 × 5 × 29 = 1,160

the numbers have common prime factors
