How can you find the scale factor from a larger figure to the smaller figure using the scale factor from the smaller to larger figure?
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
What number can be divided by 2 3 5 6 7?
This is a LCM question, so factor all and find the highest power of each prime factor. 2 is prime 3 is prime 5 is prime 6 is [2 3] 7 is prime. LCM is [2] [3] [5] [7] so the answer is 210◄
What is the least factor of 2 3 4 5 6 7 8 9 and 10?
The least factor of any number is always 1. Therefore, the least factor of 2, 3, 4, 5, 6, 7, 8, 9, and 10 is 1.
What are all the number that are factor of 7?
all perfect cubes (any number powered by 3) by adding or subtracting 1 become factor of 7 except base number as 7 and its factors.
Which number is a multiple of 7 and has 3 as a factor?
21 has 3 as a factor and is a multiple of 7, and so as 210, 105, and an infinite number of other numbers.
What number has a factor of 3 4 5 6 7?
420
What is the least common multiple of the numbers 5 7 and 9?
Factoring each number into product of primes: 5=1 x 5 7 = 1 x 7 9 = 3 x 3, 1 x 9 The number 5 is a factor of 5 only; Include 5 in answer The number 7 is a factor of 7 only; Include 7 in answer The number 3 is a factor twice of 9; Include 3x3 in answer Therefore, LCM(5,7,9) = 3 x 3 x 5 x 7 = 315 Additional content regarding LCM may be referenced at http://www.math.info/Arithmetic/LCM
Which is the smallest number that has 2 3 5 7 11 as a prime factor?
It is: 2*3*5*7*11 = 2310
What is the prime number factor of 735?
3 x 5 x 7 x 7 = 735
Is 2 and 3 a factor?
A factor of a number is an integer that divides the number evenly (without remainder). So 2 and 3 are factors of 12 (12/2 is 6 and 12/3 is 4), but 7 is not a factor of 12 (12/7 is 1 remainder 5). 2 and 3 are not factors of 5 (notice 5 is prime).
What is 105 as a factor of a prime number?
3 x 5 x 7 = 105
What is the first common factor of 5-3-7?
There is only one common factor of 5, 3, 7: 1

What is the prime factorization of 1575?
Since the number ends with 5, 5 is a factor. 3 is also a factor. Divide it by those factors, then see if you can find additional factors.
How can you tell by drawing a factor tree whether or not a number is a square number?
A factor tree tells you the prime factorization. The prime factorization can indicate a square number. Square numbers have even pairs of prime factors. 2 x 2 x 3 x 3 is a square number. 5 x 5 x 5 x 5 x 7 x 7 x 7 x 7 is a square number.
What number can be divided by 2 3 5 6 7?
This is a LCM question, so factor all and find the highest power of each prime factor. 2 is prime 3 is prime 5 is prime 6 is [2 3] 7 is prime. LCM is [2] [3] [5] [7] so the answer is 210◄
Which number is a factor of 21 but not a multiple of 7 a.2 b. 4 c. 5 d. 3?
d. 3
