What is the remainder when 189ˏ540 is divided by 27?
No remainder. It has the same rule as 3 for divisibility. Add them up and if that is divisible by 27 then the number is divisible by 27.
What numbers can go into 27 without leaving a remainder?
1, 3, 9 and 27.
Is 83 divisible by 3?
No, 83 is not divisible by 3. When a number is divisible by another number, it means that the division will result in a whole number without a remainder. In this case, when you divide 83 by 3, you get 27 with a remainder of 2, which means 83 is not divisible by 3.
What is the GCF of 405 and 486?
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 405 and 486, we can use the prime factorization method. First, we find the prime factors of both numbers: 405 = 3 x 3 x 3 x 3 x 5 and 486 = 2 x 3 x 3 x 3 x 3 x 3. Then, we identify the common prime factors, which are 3 x 3 x 3 = 27. Therefore, the GCF of 405 and 486 is 27.
An exact divisor of an number?
an exact divisor of a number is one that leaves no remainder (a remainder of zero)--example: 27 divided by 3 is 9 but 27 divided bt 4 is 6 remainder 3 so 4 is not an exact divisor of 27 but 3 is
