Question

Find the LCM andHCF of the following integers by applying the prime factorisation method 15and25

Answer 1

$\huge {Solution }$

LCM : Least common Factor .

LCM of 15 and 25 :

15 = 3 × 5

25 = 5 × 5

Here , LCM = 3 × 5 × 5 = 75 .

Hence , LCM of 15 and 25 is 75 .

HCF =Highest Common Factor

HCF of 15 and 25 :

15 = 3 × 5

25 = 5 × 5

Here , the highest common factor in 15 and 25 is 5 .

Hence , HCF of 15 and 25 is 5 .
