Divide by 1, 2, 5 and 7.
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.
1, 2, 5, 7, 10, 14, 35, 70
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70.
70 has 8 factors; 1,2,5,7,10,14,35 and 70.
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70 The common factors of 21 and 70 are 1 and 7.
Prime factors of 55 are: 5 and 11 Prime factors of 70 are: 2, 5 and 7 LCM is: 2*5*7*11 = 770
You need at least two numbers to find something in common.
The factors for 70 are: 1, 2, 5, 7, 10, 14, 35, 70.
The common factors of 49 and 70 are 1 and 7.
The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70 The factors of 97 are: 1, 97
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.
The factors of 25 are: 1, 5, 25 The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70
