The GCF is 8.
One way to approach this is to look at the difference between 72 and 80, which is 8. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. Since both 72 and 80 are divisible by 8, the greatest common factor is 8. Another 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 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8. 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 80 are 2, 2, 2, 2, and 5. The prime factors in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8.
Common factors of 72 and 80 are: 1, 2, 4, and 8.
The greatest common factor of 54 and 80 is 2.
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. 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 32 are 1, 2, 4, 8, 16, and 32. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8.
72 and 80's highest common factor is eight.
Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as 80, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.Examples:The common factors of 14 and 80 are 1 and 2; the greatest common factor is 2.The common factors of 32 and 80 are 1, 2, 4, 8, and 16; the greatest common factor is 16.The common factors of 60 and 80 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.The common factors of 70 and 80 are 1, 2, 5, and 10; the greatest common factor is 10.The common factors of 80 and 102 are 1 and 2; the greatest common factor is 2.The factors of 80 are 1,2,4,5,8,10,16,20,40 and 80. For them to have something in common, you need another set of factors to compare them to.
The greatest common factor of 52 and 80 is 4.
