5, 7, and 3 go into 105.
Oh, dude, 12 can go into any number that is a multiple of 12, 5 can go into any number that is a multiple of 5, and 3 can go into any number that is a multiple of 3. So, the number that 12, 5, and 3 can all go into is the least common multiple of 12, 5, and 3, which is 60. Like, math, man.
It is: 3*5*7 = 105
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
