140

140

131,133,137, 139

It is: 2*2*5*7 = 140 by dividing it by each prime number that has no remainder

149 is the only prime number betweeen 140 and 150.

It is 7 because as a product of its prime factors: 2*2*5*7 = 140 or as 22*5*7 = 140

7 since 7 goes into 63 and 140 evenly and 7 is a prime.

That is easy, 140 is prime.

2 x 2 x 5 x 7 = 140

140 is a composite number because it has more than two factors

Prime factorization is the finding which prime number multiply to get to make the original number. 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140 Prime: 2, 5, 7 Prime Factorization: 2 x 2 x 5 x 7

140 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

The prime numbers (factors) of 140 are: 2,5,7

All numbers have factors. Some numbers have only two factors, the number one and the number itself. These are known as prime numbers. 7 has two factors: 1 and 7. 7 is a prime number.

No, it's brilliant.

There are 34 prime numbers under 140.

140 has the prime factorization of 5 2 2 and 7.

They are not relatively primeNo. To be relatively prime they could only have the number 1 as a common factor, but they have other common factors.

Divide the number starting from the smallest prime number, which is 2. 140 / 2 = 70 70 / 2 = 35 140 can be divided by 2 twice only Next we repeat with the next prime number, which is 3. 35 is not divisible by 3 so we move on to the next prime number, which is 5 35 / 5 = 7 35 can be divided by 5 once only Next prime number is 7 7 / 7 = 1 [Your objective is to get a 1] Working could be: 140 / 2 = 70 70 / 2 = 35 35 / 5 = 7 7 / 7 = 1 Prime factorization of 140 = 2 x 2 x 5 x 7 or 2^2 x 5 x 7

The prime factorization of 140 is: 2 x 70 2 x 2 x 35 2 x 2 x 5 x 7. The prime numbers that are factors are therefore 2, 5, and 7.
