Question

Geekhawk · Answer

The answer is 21 21x3=63 and 21x4=84

Geekhawk · Answer

The greatest common factor (GCF) of 84 and 63, found using prime factorization, is 21. This was determined by identifying the common prime factors between the two numbers and multiplying them together. Thus, GCF ( 84 , 63 ) = 21 .
