No, 6 does not go evenly into 2345. A method to find out if something is divisible by 6 is... Is it divisible by 2? Is it divisible by 3? 2*3=6 So, 2 and 3 should be able to go evenly into the number.

Yes, to check for divisibility by three, use the sum of digits method: 5 + 3 + 4 = 12. Twelve is divisible by 3, so 534 is also divisible by 3

No specific method has been discovered so far,not even by the greatest mathematicians,to create a prime number or to find out all the prime numbers......but there's a way to find whether a number is prime or not,i.e,by dividing that number with the first prime nos. such as 2,3,5,7,11 and so on and seeing whether it is exactly divisible or not.If it is not,then it can be classified as a prime no.

Yes. 39105 is divisible by 9.One easy method to find out whether a number is divisible by 9 is adding each number.For example to find out whether 39105 is divisible by 9,add each number in 39105.3+9+1+0+5=18=1+8=9Therefore if a number gives 9 as total it will be divisible by 9.

No, 159398 is not divisible by 8. 1. In this case, last three digits (398) are not divisible by 8, so the given number is not divisible by 8. 2. If 159398 is divided by 8, using division method, a remainder (6) is left, so it is indivisible by 8.

The GCF is 5. Method: Because 3045 is such a large number, find the prime factors of 50 and check whether any of them divide into 3045. The prime factors of 50 are 2, 5, and 5. 3045 ÷ 5 = 609, which is not divisible by another 5, since it does not end in 5 or 0. Nor is it divisible by 2, since it is not an even number. Therefore, the greatest common factor of 50 and 3045 is 5. (3045 = 3 x 5 x 7 x 29)

No. 26 for instance the sum of the digits is 8 but not divisible by 4. 32 the sum of the digits is 5 but divisible by 4 The rules for some other numbers are 2 all even numbers are divisible by 2 3 The sum of the digits is divisible by 3 4 The last 2 numbers are divisible by 4 5 The number ends in a 0 or 5 6 The sum of the digits is divisible by 3 and is even 7 no easy method 8 The last 3 numbers are divisible by 8 9 The sum of the digits is divisible by 9
