How do you factor 5100?

Answer 1

whenever I start factoring a number I always start with the lowest Prime number and then go up. Start with 2

5100/2 = 2550

2550/2 = 1275 (this is not divisible by 2 so go to the next prime number... 3)

1275/3 = 425 (this is not divisible by 2 or 3 so go to the next prime number...5)

425/5 = 85 (this is not divisible by 2 or 3 so go to the next prime number... 5)

85/5 = 17 (this is a prime number so it can not be divide any more)

now take all the numbers you used to divide the larger number. These number will include... 2,2,3,5,5, and 17

these are all of the prime factors of 5100... 2x2x3x5x5x17=5100

Answer 2

2 x 3 x 3 x 5 x 5 x 11 = 4950
