Answer:
The largest no. that divides two numbers is known as the GCD (Greatest Common Divisor) or the HCF (Highest Common Factor). We can find it by listing down all the factors of the numbers and then selecting the common factors and then the greatest of them.
Factors of 18: 1, 2, 3, 6, 9 & 18
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Common Multiples: 1, 2, 3 & 6
Therefore,
GCD or HCF => 6
Thus, the largest number that divides 18 and 24 is 6.
