15, 45, 75, 105, 135
Itself and any of its multiples that ends with a 5
1 x 5 = 5 3 x 5 = 15
odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
No as 5, 15 and an infinite amount of other multiples of 5 are odd
No. Only odd numbers that are multiples of five.
Oh, isn't that a happy little math problem! We take the sum of all the odd multiples of five from 1 to 2007, which is 5 + 15 + 25 + ... + 2005. This sum is 100,040,000. When we divide this by ten, we get a remainder of 0, like a peaceful little stream flowing gently through the forest.
15 and 25.
they all don't 5*2=10 so all of them do not end in 5 just a half .. even multiples ends with 0, odd multiples ends with 5.
The GCF is 5.
Any number ending in 5.
That happens because 5 is an odd number. An odd number times an odd number will give you an odd product; an odd number times an even number will give you an even product. The same happens for the multiples of any other odd number.
5 is an odd number the prime factorization is 1times 5 and 5 times 1numbers which are multiples of 2 are called even no.s and others are odd numbers.
