What is the GCF of 42 and 72 and 84?
The GCF is 6.
What is the greatest common factor of 72 and 84?
The GCF of 72 and 84 is 12. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors of 84 are 2, 2, 3, and 7. The prime factors in common are 2, 2, and 3, so the greatest common factor is 2 x 2 x 3 = 12.
What is the greatest common factor of 84 72 24?
Since 72 is a multiple of 24, and the greatest common factor cannot be greater than the smallest number, the greatest common factor of 84, 72, and 24 will be the greatest common factor of 84 and 24. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. (The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.) The greatest common factor is 12. Or, you can look at the prime factors. The prime factors of 84 are 2, 2, 3, and 7. The prime factors of 24 are 2, 2, 2, and 3. (The prime factors of 72 are 2, 2, 2, 3, and 3.) The prime factors they have in common are 2, 2, and 3, so the greatest common factor is 2 x 2 x 3 = 12.
What is 84 as a product of its prime factors?
The prime factors are: 2, 3 and 7. (2 x 3 x 7 = 42)
What are the factors of 84 and 72?
1,2,3,4,6,8,9,12,18,24,36,72 1,2,3,4,6,7,12,14,21,28,42,84
Which is not a factor of 84?
84/2 42/2 21/3 7 Seven is prime, so the prime factors of 84 are: 2*2*3*7 So all numbers that are not 1, 2, 3, 7 or 84 are not factors of 84.
Which one has 3 prime numbers 14 28 42 56 70 84 or 98?
It is 70 or 42 that have exactly 3 prime factors
What are the factors and prime factors of 504?

What is the greatest common factor of 42 72 and 84?
Answer: 6Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.
