∙ 10y agouse divisibility rules to find at least four factors of the number 19
1, 2, 4 and 47
1, 2, 3 and 4
The least 4 factors of 144 are 1, 2, 3, and 4 .
Yes, 104 is a multiple of four. You can tell by using the divisibility rules : if the last two digits of a number are divisible by four, then the whole number is divisible by four. Now lets go back, in case you don't know, divisibility is simply if a smaller number, like four, can go into a larger number, like 104, perfectly;without having to use decimals.
Divisibility by 48 requires divisibility by 3 AND by 48Divisibility by 3 requires tat the digital root (sum of digits) is divisible by 3.Divisibility by 16 requires that the number formed by the last four digits is divisible by 16.Of both these are satisfied by a number then it is divisible by 48.
Just knowing the divisibility rules for the first four prime factors (2, 3, 5 and 7) will help find the prime factorizations of a large percentage of the numbers you will encounter. At the very least, dividing your original number by those factors should cut it down to a manageable size. The first thing you do when starting a prime factorization is notice whether the number is even. If it is, you can take out two as a factor. If not, you can skip over it. The same with 3 and 5. If you know they are not factors just by looking at the number, it saves a lot of trial and error.
1, because everything is divisible by 1. 2, because it's even. 3, because the sum of the digits is a multiple of 3. 4, because the last two numbers are a multiple of 4.
Using the divisibility rules for the numbers 2,3,4,5,6,9, and 10, four hundred seventy is divisible by: 2, 5, and 10
1) Durability, divisibility, Acceptability , uniformity
Every integer is divisible by 1. So 1 is a factor. The number ends in a 2 and so is even. Therefore, 2 is a factor. The sum of the digits is 3+1+2 = 6 which is divisible by 3 so 3 is a factor. 2 and 3 are both factors so 2*3 = 6 is a factor. So, four factors are 1, 2, 3 and 6.
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.
