Even if that was 2 x 4 x 5, it wouldn't be a prime factorization because 4 isn't a Prime number. The full prime factorization of 40 is 2 x 2 x 2 x 5.
As a product of its prime factors: 5*7*7 = 245
A prime factorization
The product of the prime factors of 26 is the composite number 26.
As a product of its prime factors: 2*2*1213 = 4852
The prime factorization of 245 is 5 x 7 x 75 x 7 x 7 = 2455 x 7 x 7 = 245The process of prime factorisation is one of repeated division by primes, while obtaining a quotient without a remainder, until the process yields a quotient of 1 245 is not divisible by 2 or by 3245 ÷ 5 = 49 ................................. 5 is a prime factor of 24549 is not divisible by 549 ÷ 7 = 7 ..................................... 7 is a prime factor of 2457 ÷ 7 = 1 ....................................... 7 is a prime factor of 245 So the prime factors of 245 are 5, 7 and 7
As a product of its prime factors: 5*7*7 = 245
245 = 5 x 7 x 7
As a product of its prime factors: 5*7*7 = 245
As a product of its prime factors: 5*7*7 = 245
To find the prime factors of 490, we start by dividing it by the smallest prime number, which is 2. 490 รท 2 = 245. Next, we divide 245 by the next smallest prime number, which is 5. 245 รท 5 = 49. Finally, 49 is a square of 7, which is a prime number. Therefore, the prime factors of 490 are 2 x 5 x 7 x 7.
LCM of a prime number and a composite number is equal to their product if the latter is not divisible by the former. 5 is a prime number and 49 is a composite number. 49 is not divisible by 5. So, LCM(5,49) = 5 x 49 = 245. Actually the reason behind this is that both(5 and 49) do not share any common factors except 1, so the LCM is equal to the product.
5 x 7 x 7 = 245
5*72 = 245
5 x 7 x 7 = 245
They are 5 and 7
Any product resulting from 245 being multiplied by another number. (ie: 2*245; 34*245)
The prime factorization for 245 is 7^2 x 5
