The GCF is 1.
It is: 1
There is neither a greatest common factor nor common factors of a single number, such as 72, 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.The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The prime factors of 72 are 2, 2, 2, 3, and 3.Examples:The common factors of 21 and 72 are 1 and 3; the greatest common factor is 3.The common factors of 56 and 72 are 1, 2, 4, and 8; the greatest common factor is 8.The common factors of 72 and 100 are 1, 2, and 4;the greatest common factor i s 4.MoreThe question has a problem, because a greatest common factor is a factor "common" to two or more numbers. A single number has no "common" factor.An example of greatest common factor:Find the greatest common factor of 49 and 21.- The factors of 49 are 1, 7, and 49.- The factors of 21 are 1, 3, 7, and 21.The greatest factor common to both numbers is 7.
The greatest common factor of 42 and 72 is 6 Gcf stands for Greatest Common Factor, The gcf of 42 and 72 is the largest positive number that is a factor of both 42 and 72. The positive factors of 42 (the integral divisors of 42) are: 1, 2, 3, 6, 7, 14, 21, and 42. The positive factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 36, and 72. Therefore the gcf of 42 and 72 is 6, as the greatest factor that 42 and 72 have in common.
7 is the greatest common factor.
The greatest common factor is 7
56 and 72
The greatest common factor of 280 and 7 is 7.
The greatest common factor of 7 and 28 is 7.
The greatest common factor of 7 and 112 is 7.
The greatest common factor of 21 and 77 is 7.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 72 and 210 is 6
The GCF of 21 and 72 is 3Definition: 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 the 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 21 are 1, 3, 7, and 21.The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The common factors are 1 and 3. Therefore, the greatest common factor is 3.By inspection:21 is divisible by 3 and 7 only 72 is divisible by 2, 3, 4, 6, 12, 18, 26, 36The greatest common factor is 3
