What is the greatest common factor osb42 and 63?

We found the factors and prime factorization of 42 and 63. The biggest common factor number is the GCF number. So the greatest common factor 42 and 63 is 21.

Step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
