HCF highest common factor

LCM of 4 ,6

2 is the division of 4 and 6.

2÷4=2 and 2÷6=3

first we divide 4 and 6 with two.

then there is a remaining 2 and 3.

it is only divided by 2 (2÷2=1).

Answer 2

Answer:

Start by writing 24 and 180 as the product of their prime factors. To find the HCF, find any prime factors that are in common between the products. Each product contains two 2s and one 3, so use these for the HCF. To find the LCM, multiply the HCF by all the numbers in the products that have not yet been used.
