The prime factorization of 40 is 2^3 * 5, or 2 * 2 * 2 * 5.
Prime factorization is easy. Just start dividing a number by other numbers you know will divide it evenly. Then divide the result numbers again, by numbers that will divide evenly. Continue the process until you get answers that can't be divided by anything except themselves and one. Those answers are *prime* numbers.
Starting with 40, we observe that we can divide by 10, to get 4 * 10. But 4 is 2 * 2. And 10 is 2 * 5. Since 2 can't be divided anymore, nor can 5 (they're both prime), the prime factorization is:
4: 2 * 2
10: 2 * 5
Combine all the factors: 2 * 2 * 2 * 5.

To find the Greatest Common Factor (GCF) of 24, 40, and 48, we first need to find the prime factorization of each number. The prime factorization of 24 is 2^3 * 3, the prime factorization of 40 is 2^3 * 5, and the prime factorization of 48 is 2^4 * 3. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^3 = 8. Therefore, the GCF of 24, 40, and 48 is 8.
1, 2, 4, 5, 8, 10, 20 and 40 are the prime factors of 40
It is: 2*2*2*5 = 40
40 = 23 x 5
The GCF of 35 and 40 is 5. The prime factorization of 35 is 5*7. The prime factorization of 40 is 2*2*2*5 The GCF is 5, which is the only common factor.
