What are the divisors of a number?
The divisor is any number that divides another number. However, a factor is a divisor that divides the number completely, leaving no remainder. Thus all factors of a number are its divisors.
What is the fastest way to find the positive divisors?
Example: 4 has the divisors 2 and 1. And 2+1=3 is less than 4, so 4 is an insufficient number.
What are all factors of 72?
Therefore 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72 are the divisors of 72.
What are the prime factors of 72?
So the prime factors of 72 are written as 72 = 2 × 2 × 2 × 3 × 3.
What is a true divisor in math?
A positive proper divisor is a positive divisor of a number, excluding itself. For example, 1, 2, and 3 are positive proper factors of 6, but 6 itself is not. The number of proper divisors of is therefore given by. where is the divider function.
What is the HCF of 45 and 30?
Answer: HCF of 45 and 30 is 15. Highest Common Factor (HCF) of 45 and 30 is the highest possible number that divides the two numbers exactly with no remainder.
