3 x 13 = 39
13 and 33 x 13
2 times 39 is the only possible way
78 / 2 = 39 39 / 3 = 13 So the prime fact. is 2 x 3 x 13
To find the prime factorization of a number, it helps to divide it by any obvious factors. In this case, 156 is even so we can divide by 2. Do this and we get 78, which is also even. Divide by 2 again and we get 39, which is divisible by 3. Do that and we get 13 which is prime. Thus the prime factorization of 156 is 2x2x3x13. If we want to use exponents this can be written as 22x3x13
The prime factorization of 39 is 3 X 13.
The prime factorization of 39 is: 13 * 3 *1
39=3x133 x 13 = 39
The lowest prime number that will divide evenly into 39 is 3, so 3 is a prime factor of 39. 39/3 = 13, and 13 is a prime number that is also a factor of 39. The prime factorization of 39 is 3 x 13.
3 x 13 = 39
3 x 13 = 39
39 = 3 x 13
31 x 131 = 39
3 x 13
The GCF of 27 and 39 is 3. The prime factorization of 27 is 3*3*3 The prime factorization of 39 is 3*13 So the GCF of 27 and 39 is 3.
156 = 4 * 39 = 22 * 39
3 and 13
