The factors of 22 are 1, 2, 11, and 22. The factors of 55 are 1, 5, 11, and 55. The common factors are 1 and 11. Therefore, the greatest common factor is 11. The greatest common factor can also be find by determining the prime factors and multiplying the common prime factors together. The prime factors of 22 are 2 and 11. The prime factors of 55 are 5 and 11. The common prime factors are a single 11, so the greatest common factor is 11.
The common factors are 1, 2, 11, and 22. The greatest common factor is 22.
Answer: 11Note that 11 is a factor of 22 and 33. Since 22=11x2 and 33=11x3, then 11 is the greatest common factor. The only factors of 22 and 1, 2, 11 and 22. For 33 they are 1,3,11, and 33.The only common factor other than 1 is 11.
11 and 22 or 22 and 33
The GCF of 22 and 44 is 22. Since 22 evenly divides 44 and thus is a factor of 44, and is also the largest factor of itself, the greatest common factor is 22. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 22 are 1, 2, 11, and 22. The factors of 44 are 1, 2, 4, 11, 22, and 44. The common factors are 1, 2, 11, and 22. Therefore, the greatest common factor is 22. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 22 are 2 and 11. The prime factors of 44 are 2, 2, and 11. The prime factors in common are 2 and 11, so the greatest common factor is 2 x 11 = 22.
