The factors of 11 are 1 and 11. Neither is one more than a multiple of 6.
the greatest multiple of four less than 100, is 96
48 and 36

The term Greatest Common Multiple has no meaning; there is no such thing as a greatest multiple. There are the terms: Lowest Common Multiple (LCM) which is the smallest positive (whole) number which is a multiple of two, or more, numbers. eg LCM(4, 10) = 20 as 20 is the first number greater than 0 which is a multiple of both 4 and 10. Highest Common Factor (HCF), or Greatest Common Factor (GCF) which is the largest positive (whole) number that divides into all the numbers (without remainder); this can also said to be the largest positive number (whole) number which has all the numbers as some multiple of it. eg HCF(25, 60) = 5 since 5 is the highest positive (whole) number which divides into 25 and 60 (without remainder). The Lowest Common Factor of any set of numbers is 1 as 1 is the smallest positive (whole) number and it divides into every other (whole) number without remainder; this is not very useful.
Eleven has no such factor.
No.
254 cannot have a greatest common factor. To have a greatest common factor, there must be more than one number involved
You need more than one number to have a COMMON factor since common implies more than one.
In order to have a "greatest common factor" you need to have more than one number, so that 175 has factor in common with another number.
"Common" requires more than one...
No.
The greatest common factor can't be a smaller number than the least common factor, but if you meant least common multiple, 7 and 28 have a GCF of 7 and an LCM of 28.
You need more than one number to find a GCF.
Need more than one number to have a COMMON factor. Common means both numbers have it as a factor.
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.
