You need at least two numbers to find a GCF. If that's 5 and 7, the GCF is 1.
The GCF is 11.
HCF(55, 77, 143) = 11.

The GCF is 3.The GCF/HCF of 42 and 57 is 3. The GCF is 3.
The hcf is 12
The GCF is 2.
If you mean 24 and 36 then the HCF is 12
If you mean: 21, 49 and 84 then the HCF is 7
The GCF/HCF of 57 and 87 is 3.The highest common factor (HCF) is 3.
It is: 19
The HCF of the numbers 38 and 57 is 19.
The GCF is 3.
47/57 is in its simplest form. hcf(47, 57) = 1.
57/76 = 3/4 by dividing the numerator and denominator by hcf which is 19
The GCF is 50.
The GCF is 3.The GCF/HCF of 42 and 57 is 3. The GCF is 3.
The prime factors of these numbers are:- 57 = 3 x 19 93 = 3 x 31 The only common factor and therefore the HCF is 3.
The highest common factor of 3 and 5 is ' 1 '.The highest common multiple of 3 and 5 that's less than 57 is 45 .
You need at least two numbers to find both of those. If that's 5 and 7, the GCF is 1, the LCM is 35.
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
