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.
To find the factors that go into 70 and 160, we first need to factorize each number. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160. The common factors between 70 and 160 are 1, 2, 5, and 10.
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.
