20 and 30
All numbers have at least one common factor.
The number one has one factor. Prime numbers have two.
Both 10 and 20 are two-digit numbers that are factors of 20.
1 is the number less than fifty with the fewest number of factors. All other numbers have at least two factors (1, and the integer itself).
Four. They are 14, 21, 28, and 42.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
25
The number one has one factor. Prime numbers have two.
It is 1 which has only one factor followd by any of the prime numbers which have only two factors
Both 10 and 20 are two-digit numbers that are factors of 20.
72 and 84 have loads of factors.
That would be 1. The only factor of 1 is 1. All other whole numbers have at least two factors. Prime numbers have exactly two factors, while composite numbers have more than two factors.
They are: 1 2 3 5 7 11 13 17 19 and 23 which are all prime numbers having only 2 factors except for 1 which has only one factor which is itself.
There are 21 two-digit prime numbers.
If you're asking about distinct prime factors, there are eight numbers tied with three of them. If not, 64 has six twos.
1 is the number less than fifty with the fewest number of factors. All other numbers have at least two factors (1, and the integer itself).
what is the least possible sum of two 4-digit numbers?what is the least possible sum of two 4-digit numbers?
The two-digit whole numbers that have no odd factors except 1 are the powers of 2, as these numbers are only divisible by 1 and themselves. The two-digit powers of 2 are 16, 32, 64, and 128. However, 128 is not a two-digit number, so we only consider 16, 32, and 64. Therefore, there are three two-digit whole numbers that meet the criteria: 16, 32, and 64.
