38 = 2 X 19
Two.
As a product of its prime factors: 2*61 = 122
As a product of its prime factors: 5*7*11 = 385
As a product of its prime factors: 2*2*5*5 = 100
As a product of its prime factors in exponents: 2^3 times 5^2 = 200
An example of a product of primes is (2 \times 3 \times 5). This expression multiplies the prime numbers 2, 3, and 5 together, resulting in 30. Each factor in this product is a prime number, demonstrating how primes can combine to form a composite number.
48 = 2 × 2 × 2 × 2 × 3
There are no two primes whose product is 50.There are no two primes whose product is 50.There are no two primes whose product is 50.There are no two primes whose product is 50.
i think it is 10 times 11 but it said it was wrong for me on hegarty maths
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.
102 = 2*3*17
Factor out each number into primes to get: 38 = 2 * 19 20 = 2² * 5 28 = 2² * 7 Count the maximum number of distinct primes for all of these values. For instance, if 20 and 28 both have the maximum number of "2" 2, then write out 2². If one number has a prime factor while the rest of the number doesn't, then write out that prime factor. Following these steps, we have this product: 2² * 5 * 19 * 7 = 4 * 5 * 7 * 19 = 2660 So that is the LCM of the given numbers.
