'5' & '15' are odd numbers less than 20 , and are also multiples of '5'.
5, 10, 15, 20, 25, 30, 35... etc.
To find the greatest common factor (GCF) of 15, 20, and 35, we need to determine the largest number that divides evenly into all three numbers. The prime factorization of 15 is 3 x 5, 20 is 2^2 x 5, and 35 is 5 x 7. The common factors among the three numbers are 5, as it appears in all three prime factorizations. Therefore, the GCF of 15, 20, and 35 is 5.
To find the HCF, you first have to express both numbers as the product of their prime factors: 15 = 3x5 20 = 2x2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor. Therefore the HCF of 15 and 20 is 5.
The greatest common factor of 10, 15, and 20 is 5.A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 10 are 1, 2, 5, and 10.The factors of 15 are 1, 3, 5, and 15.The factors of 20 are 1, 2, 4, 5, 10, and 20.The common factors are 1 and 5. Therefore, the greatest common factor is 5.If you mean: 10, 15 and 20 then it is 5 that is the greatest common factor
The two numbers are 5 and 15. 5 + 15 = 20. 15 - 5 = 10.
15 and 5
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
5, 10, 15, 20
Multiples. The numbers 10, 15 and 20 are multiples of 5.
set of odd numbers divisible by 2 between 10 and 20
The two numbers that solve this problem are 5 and 15. The sum of 5 and 15 is equal to 20, and 15 is indeed 3 times 5.
no 5 is not a composite number 10 15 20 and 25 are composite
15 is not prime, so they cannot be.
The GCF is 5.
