What is the prime factorization of 63 using factor tree?

Prime Factor tree of 63. We note that '63' is an odd number , because it does NOT end in 0,2,4,6,8 So it will not divide by ;2 So we try the next prime number, which is '3' 3)63 = 21 Keep on dividing by '3' until it will not divide any further by '3' 3)21 = 7 Since '3' will not divide into '7' and '7' is a prime number, divide '7' into itself , to reduce to '1' 7)7 = 1 So the prime factor tree/stepladder of '63' is 3,3,7. This can be expressed as 3^(2) x 7^(1) = 3^(2) x 7 .
