The number(s) that will go into 105 are 1, 3, 5, 7, 15, 21, 35, and 105.
1, 3, 5, 7, 15, 21, 35, 105.
1. As 7 is a prime number.
The numbers 5, 7, and 3 all go into their least common multiple (LCM), which is 105. This means that 105 is the smallest number that is a multiple of all three numbers. In general, any multiple of 105 will also be divisible by 5, 7, and 3.
3*5*7=105◄
As a product of its prime factors: 3*5*7 = 105
Lets see if 217 is a prime or composite number. 15 times 15 is 225, so we will try the first prime numbers up to 15. They are 2, 3, 5, 7, 11, and 13. Will 2 go into 217? No 7 is odd. Will 3 go into 217. If we add the integers, they add up to 10. 3 does not go into 10. Will 5 go into 217. No. It does not end in a 0 or a 5. Will 7 go into 217. Lets see. Will 7 go into 21? Yes it goes in an even number of times. How about that. Will seven go into 7. Yes it goes in an even number of times. You can show the math.
