What is the greatest common factor of 30 42 and 56?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. The common factors are 1 and 2. Therefore, 2 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 30 are 2, 3, and 5. The prime factors of 42 are 2, 3, and 7. The prime factors of 56 are 2, 2, 2, and 7. The prime factors in common are a single 2, so the greatest common factor is 2.
What is are all the common factors of 28 and 42?
The prime factors of 28 are 2,2 and 7 The prime factors of 42 are 2,3 and 7 Thus the common factors are 1,2,7 and 14.
What are the common factors of 42 and 23?
To work this out, you first have to split the numbers down into their prime factors: 42 = 2x3x7 23 = 23 There are no common prime factors. This means that the only common factor of 42 and 23 is 1.
What are the common factors of 42 and 43?
43 is a prime number so the common factors of 43 and 42 are 1
What is the greatest common factor of 30 42 and 48?
The GCF of 30, 42, and 48 is 6.Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30.Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42.Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.GCF (30, 42, 48) = 6
What prime factors do 42 and 21 have in common?
7
What is the least common multiple of 14 and 42?
The LCM of 14 and 42 is 42. The simplest method to determine the least common multiple in this case is to notice that 42 is a multiple of 14. Since 42 is a multiple of 14, the least common multiple is 42. To determine the least common multiple of two numbers, you can also determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 14 are 2 and 7. The prime factors of 42 are 2, 3, and 7. The greatest common factor of 14 and 42 is 14. So, the least common multiple of 14 and 42 is (2x7) x (2x3x7) ÷ 14 = 42.
What is the greatest common factor of 35 and 42?
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 35 are 5 and 7. The prime factors of 42 are 2, 3, and 7. The common prime factors are a single 7, so the greatest common factor is 7.
What is the Prime factor of 42 and 660?
42 - The prime factors are: 2, 3 and 7660 - The prime factors are: 2, 3, 5 and 11
What are the common factors of 30 and 42?
The common factors of 30 and 42 are 1, 2, 3 and 6
Two common factors of 42 and 231?
To find the common factors of 42 and 231, we first need to find the prime factorization of each number. The prime factorization of 42 is 2 x 3 x 7, and the prime factorization of 231 is 3 x 7 x 11. The common factors of 42 and 231 are the prime numbers that appear in both factorizations, which are 3 and 7. Therefore, the two common factors of 42 and 231 are 3 and 7.
Is 1 the greatest common factor of 42 and 90?
No, it is 6. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The common factors are 1, 2, 3, and 6, so the greatest common factor is 6. You can also determine this by looking at the prime factors. The prime factors of 42 are 2, 3, and 7. The prime factors of 90 are 2, 3, 3, and 5. The prime factors they have in common are 2 and 3, so the greatest common factor is 2 x 3 = 6.
