450 = 2 x 3 x 3 x 5 x 5
I believe it is 1 since 17 is a prime
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
To find the greatest common factor (GCF) of 180, 450, and 420, we first need to find the prime factorization of each number. The prime factorization of 180 is 2^2 x 3^2 x 5, the prime factorization of 450 is 2 x 3^2 x 5^2, and the prime factorization of 420 is 2^2 x 3 x 5 x 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 x 3 = 12. Therefore, the greatest common factor of 180, 450, and 420 is 12.
1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, and 450
