23 x 53 = 1000
Prime factorization of 275 = 52 x 11 Prime factorization of 1000 = 23 x 53 gcf(275, 1000) = 52 = 25.
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
1,024 because all the numbers between 1 and 1000 that have 2 as their only prime factor are 2,4,8,16,32,64,128,265,512 The patern is that 2 times 2 =4, 4 times 2=8, 8 times 2=16 ect. and 512 times 2 = 1,024
23 x 53 = 1000
49/1000 can not be reduced because 7, the only prime factor of 49, is not a factor of 1000.

The prime factors of 954 are 2, 3, 3, and 53. The prime factors of 1000 are 2, 2, 2, 5, 5, and 5. The common prime factors are a single 2, so the greatest common factor is 2.
The GCF is 1.
Prime factorization of 275 = 52 x 11 Prime factorization of 1000 = 23 x 53 gcf(275, 1000) = 52 = 25.
There is no common prime factor for 133 and 1000 and so the only number that goes into both is 1.
