28 is a factor of 56, and 28 is also a factor of itself. So the highest common factor of 28 and 56 is 28.
both numbers have a common factor of 7 divide each by 7: 21/28 = 3/4
The greatest common factor of 28 and 20 is 4.
The factors of 28 are: 1, 2, 4, 7, 14, 28The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42The factors of 63 are: 1, 3, 7, 9, 21, 63The common factors are: 1, 7The Greatest Common Factor (GCF) is: 7The GCF is: 7The GCF is 7.
The greatest common factor of 14, 28, and 70 is 14.
The GCF is 7.
The highest common factor is 7.
The common multiples of 21 and 28 are 84, 168, 252, 336, ... and so on, never ending; so there is no real Highest Common Multiple.Do you mean:Highest Common Factor - the highest number which divides both 21 and 28 which is 7; orLowest Common Multiple - the lowest number which is a multiple of both 21 and 28 which is 84.
The highest common factor of the numbers 28, 84 and 91 is 7.
The highest common factor (HCF) is 7.
The highest common factor is 4.
The Greatest Common Factor of 15, 21, 28: 1
4 is the highest common factor of 28 and 32
The GCF is 28.
The Greatest Common Factor (GCF) is: 28
To find the highest common factor (HCF) of 504 and 700, we first need to factorize both numbers. The prime factors of 504 are 2^3 x 3^2 x 7, and the prime factors of 700 are 2^2 x 5^2 x 7. To find the HCF, we take the common prime factors with the lowest exponent, which are 2^2 x 7 = 28. Therefore, the highest common factor of 504 and 700 is 28.
1 and the highest common factor is 4
