A factor = a number which can be divided into the given number with no remainder. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, 70.
The factors of 28 are: 1, 2, 4, 7, 14, 28. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70.
They have the same number of factors.
If the sum of all a number's factors (apart from itself) is equal to the original number, then the number is perfect. If this sum is less than the number, it is deficient. If the sum is more than the number, it is abundant. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35 and 70. 1+2+5+7+10+14+35 = 74. Thus the number 70 is abundant.
Since 35 is a factor of 70, all of its factors are common.
1,2,5,7,10,14,35,70
In order to find the factors of a number you first have to break it down into its prime factors. In this case, 70 can be broken down as follows: 70 = 2x5x7 To find other factors (apart from 1) you need to multiply any combination of these prime factors together. Doing this gives us the factors of 70 as: 1, 2, 5, 7, 10, 14, 35 and 70.
The odd factors of 70 are: 1, 5, 7, and 35. The sum of these factors is 48.
To find the HCH write down all the factors of each number. Hence# 70 ; 1,2,5,7,10,14, 35 & 70. 98 ; 1,2,7,7,14, 49 & 98 The factors common to both numbers are 2,7,14 Hence '14' is the HCF.
Well, darling, the smallest number with 2, 5, and 7 as prime factors is 70. You see, 2 x 5 x 7 equals 70, and that's the tiniest number you can whip up with those prime factors. So, there you have it, sweet cheeks, the answer is 70.
The number is 54. It is greater than 36 and less than 70. One of its factors is 9 and it is an even number.
70 is a composite number because it has more than two factors
