22 x 7 = 28
2 and 7 are the prime factors of 28.
Factors of 28 are 1, 2, 4, 7, 14, and 28. Factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. The only common factors of 28 and 66 are 1 and 2.
No since it is an even number it has 2 as a factor. If the factors are the number itself and 1 it is prime. If there are more factors it is not. 28 has many more factors.28=22 x7So 2 and 4 and 7 are all factors as is 14.
The prime factorization of 28 is 2 * 2 * 7 or 2^2 * 77x2x2
20, 21, 22
28 is not a factor of 7 and 2, but 7 and 2 are factors of 28. 28's prime factorization is 22 * 7
The factors of 112 are 1, 2, 4, 7, 8, 14, 16, 28, 56, 112. None of them differ by 22.
LCM is 28, which is the multiple of the highest power of prime factors in the given numbers (22 x 7).
Answer: 2 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 14 are 1, 2, 7, and 14. The factors of 22 are 1, 2, 11, and 22. The factors of 28 are 1, 2, 4, 7, 14, and 28. The common factors are 1 and 2. Therefore, the greatest common factor is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 14 are 2 and 7. The prime factors of 22 are 2 and 11. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 2, so the greatest common factor is 2.
