It is: 51*72 = 245
5 x 72 = 245
175/245 = 35/49 = 5/7 these are both prime numbers
To find the prime factorization it helps to first divide by obvious divisors. In this case, the number ends in a 5, so we know it can divide by 5. Do this and you get 49. This is known from times tables to be 7x7. Thus the prime factorization of 245 is 5x7x7.
117 = 3 × 3 × 13245 = 5 × 7 × 7
The prime factorization for 245 is 7^2 x 5
245 = 5x72
51 x 72 = 245
5 x 72 = 245
245 = 51 x 72
145 = 51 x 291
It is: 51*72 = 245
245 / 549 / 77The answer is 51 * 72
245 = 5 × 72
245 = 5 * 7 * 7
The prime factorization of 245 is: 5 x 7 x 7
The factors of 245 are 1, 5, 7, 35, 49, and 245.The prime factors of 245 are 5, 7, and 7.Determining the prime factors:The process of prime factorization is one of repeated division by primes, while obtaining a quotient without a remainder, until the process yields a quotient of 1245 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 245So the prime factorization of 245 are 5 x 7 x 7 or, in index form (in other words, using exponents), 5 x 72.
