You need at least two numbers to find a GCF. If that's 4 and 9, the GCF is 1.
The HCF of both numbers is 1
The HCF of both numbers is 1
The HCF of both numbers is 7
HCF is the highest common factor of two or more numbers. HCF of 28, 35 and 49 is 7.
The HCF of both numbers is 1
The HCF of the given two numbers is 7
The GCF is 7.
HCF is the highest common factor of two or more numbers. HCF of 56 and 49 is 7.
The GCF is 7.
The first step when finding an HCF is to break the numbers down into their prime factors. In this case we get: 21 = 3x7 49 = 7x7 The next step is to identify any common prime factors. In this case both numbers have a 7 as a prime factor. There are no more common prime factors, and thus the HCF of 21 and 49 is 7.
14 = 7 x 2 & 49 = 7 x 7 '7' is common to both numbers, so seven is the HCF ( Highest common factor).
Interesting, the highest one would be (1), and what I am currently thinking of is how could you find such big numbers, and yet the HCF of them is 1!
