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.
First you would list all of the factors of each number. The factors of 42 are 1, 2, 21, 3, 14, 6, 7, 42. The factors of 70 are 1, 2, 35, 5, 14, 7, 10. Then you would find out which factors are common between them: 1, 2, 7. The greatest is 7.
70 has eight factors: 1, 2, 5, 7, 10, 14, 35, 70.
The prime factors of 18 are 2, 3, and 3. The prime factors of 70 are 2, 5, and 7. The prime factors that 18 and 70 have in common are a single 2.
The factors of seventy are 1, 2, 5, 7, 10, 14, 35, and 70.
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.
1,2,5,7,10,14,35,70
1, 2, 5, 7, 10, 14, 35, 70
1,5,7,35Since 35 is a factor of 70, all of its factors are common.
The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 7.
Use a factor tree. 70 Divide by two. 35,2 Divide by five. 7,5,2 Stop. All the factors are prime. 2 x 5 x 7 = 70
The common factors of 30, 50, and 70 are: 1, 2, 5, and 10.
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.
