We need to know what number the square is a factor of.
Oh, dude, the largest square factor of 20 is 4. Like, you take the number 20 and see what number can be squared to give you 20, and that's 4. So, yeah, 4 is the largest square factor of 20. Cool, right?
There are 3 factor pairs of 63: 63 = 1 x 63 63 = 3 x 21 63 = 7 x 9
The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. To find the GCF of 28 and 63, we need to list the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28, while the factors of 63 are 1, 3, 7, 9, 21, and 63. The largest number that appears in both lists is 7, so the GCF of 28 and 63 is 7.
The greatest common factor is 63
63 has a square factor, but no equal ones.
The largest perfect square factor of 48 is 16.
The largest square factor of 557 is 1 because 557 is a prime number
