How do you find all the factors of 63?
The rules of divisibility tell you that 63 is divisible by 1 (because all integers are), 3 (because its digits total a multiple of 3) and 9 (because its digits total a multiple of 9) Dividing those numbers into 63 gives you the other three (63, 21 and 7) (1, 3, 7, 9, 21, 63)
What are the least four factors of 780 using the divisibility rule?
780 is divisible by 2 because it's even. 780 is divisible by 3 because its digits total a multiple of 3. 780 is divisible by 5 because it ends in a 0. 780 is divisible by 10 because it ends in a 0.
How do you know if 436 is divisible by 3?
Add the digits. If the total is divisible by three, the original number is divisible by three. It's not and it's not.

What numbers between 2 3 4 10 9 6 5 is divisible in 372 and why?
372 is divisible by 2 because it's even 3 because the sum of its digits is a multiple of 3 4 because the last two digits are a multiple of 4 6 because its an even multiple of 3 372 is not divisible by 5 because it doesn't end in a 5 or 0 9 because its digits do not total a multiple of 9 10 because it doesn't end in a zero.
How do you find out if a number is divisible by three?
Add up the digits. If that total is a multiple of 3, so is the original number.
What is the rule to determine if a number is divisible by 12?
That the number is divisible by 4* and the sum of its digits is a multiple of 3. *If the number has three of more digits then it is only necessary to look at the tens and units to determine if it is divisible by 4, as 4 is a factor of 100 and therefore of any multiple of 100. Examples : 75 : is not divisible by 4 although its digits total 12 which is a multiple of 3. 132 : is divisible by 4 as 32 is divisible by 4, and its digits total 6 which is divisible by 3, then 132 is divisible by 12.
What is the multiple of three out of these numbers 285770126176410452650?
I'll guess those are three-digit numbers. The way to find if a number is a multiple of 3 is to total its digits. If that total is a multiple of 3, the whole number is a multiple of 3. 285 and 126, yes. 770, 176, 410, 452, 650, no.
How would you determine whether 9 is a factor of 291?
Add up the digits of 291. If they total a multiple of 9, 9 is a factor.
