Which is the least common factor 18 or 21?
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1. Factorizations: 18-3x3x2 21-7×3
How to get factors of 18 and 21?
Getting factors is done by dividing 18,21 with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors. Factors are whole numbers or integers that are multiplied together to produce a given number. The integers or whole numbers multiplied are factors of the given number.
How to find the factors of the number 27?
The steps to find the factors are: 1 First, write the number 27 in your notebook. 2 Find the two numbers, which on multiplication gives 27, say 3 and 9, such as 3 × 9 = 27. 3 We know 3 is a prime number that has only two factors, i.e. 1 and the number itself. So, we cannot further factorize it. (i.e.) 3 = 1 × 3
