2 x 5 x 7 = 70
The prime factors of 70 are 2,5 and 7 so their product is 70. This will happen whenever the prime factors occur only once. When we factor 70 into primes, we are asking for those primes who product is equal to 70. However, sometimes we get one or more primes raise to a power in the prime factorization. In this case, the prime raised to a power is no longer a prime so the product of prime factors is less than the number.
The greatest common factor of 70 and 80 is 10. The prime factorization of 70 is 2*5*7 The prime factorization of 80 is 2*2*2*2*5 The GCF is 2*5 = 10
70 is an even number and the only even prime is 2. This tells you right away that 70 is composite.Also, 70=2 X 5 X 7, so the prime factorization also shows you it is composite.70 is a composite number because it has at least one positive factor other than one or itself.
14 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors are 1, 2, 7, and 14. Therefore, the greatest common factor is 14. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 28 are 2, 2, and 7. The prime factors of 70 are 2, 5, and 7. The prime factors in common are 2 and 7, so the greatest common factor is 2 x 7 = 14.

Greatest Prime Factor of 70The prime factorization of 70 is 2 X 5 X 7, so the greatest prime factor in the prime factorization of 70 is 7.
Any non-zero product of 70 must be divisible by 70 and so it cannot be a prime.
because 70 is an even number, and every even number has 2 as a factor.
2 x 5 x 7 = 70
1, 10, 14, 35, 70
Itself and one
7
2 and 7 are prime numbers less than 10 that are factors of 42 and 70.
2 x 5 x 7 = 70
2 x 5 x 7 = 70
As a product of its prime factors: 2*5*7 = 70
