A factor tree breaks a number down into it's prime numbers.A prime number is a number that can only be divided by 1 and itself.For example: 3 is a prime number, because the only numbers that can be divided evenly into 3 are 1 and 3.Your number is 77. I can tell by looking at the number that it is divisible by 7 (note the double 7's in 77)77 / 7 = 11.This means that 7 * 11 = 77Your factor tree would look like:......77....../ \.....7*11Now we see if 7 and 11 can be broken down into smaller prime factors.Fortunately for us, 7 is already a prime number.And, as luck would have it, 11 is also a prime number.This completes the factor tree of 77.
