Question

what is hcf and lcm explain in more details​

Answer 1

$\huge\bold{HEY:)-}$

HCF = highest common factor

LCM= least common multiple

Answer 2

Answer:

H. C. F means Highest Common Factor

Take two numbers 15 and 45

Factors of 15 are 1, 15 , 3, 5

Factors of 45 are 1, 45, 3, 15, 5, 9

Now, the common numbers are 15, 3 and 5

15 is the highest number.

So 15 in the hcf

LCM:- Lowest common multiple

Multiples of 15 = 15, 30, 45

Multiples of 45 = 45, 90, 135

Here, the lowest multiple which is common in both the numbers is 45

Therefore the lcm is 45
