No it is not. 1547 = 7x13x17
Start with the prime factorization. You can find that with a factor tree. 1547 221,7 17,13,7 So you know that 1, 7, 13 and 17 are factors of 1547. Dividing them into 1547 gives you the other four. 1, 7, 13, 17, 91, 119, 221, 1547
The first step in finding the greatest common factor is to break the numbers down into their prime factors: 663=3x13x17 1547=7x13x17 The next step is to identify any common factors. In this case, the common prime factors are 13 and 17. To find the greatest common factor we multiply these together: 13x17=221 So 221 is the GCF of 663 and 1547.
1547 = 7 x 13 x 17
Damien divides 1547 by 17 and gets 91. Damien knows that 7 x 13 = 91. Since 7 and 13 are prime numbers, Damien has found them all.
91
The GCF is 91.
Yes. Any time three is a factor, it is a prime factor.
It is a factor of 132, not a prime factor.
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.
7 x 13 x 17
7 x 13 x 17
