To find the largest odd natural number that is a factor of 120, we first need to factorize 120 into its prime factors, which are 2^3 * 3 * 5. Since we are looking for an odd factor, we can ignore the factor of 2. The largest odd factor of 120 is then 3, as it is the largest odd prime factor present in the prime factorization of 120.
120 = 2 * 2 * 2 * 3 * 5 Written as a product of powers is (2^3) * 3 * 5
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime
120 is not a prime and no prime numbers equal a composite (ie non-prime).
No, 120 and 835 are not relatively prime.
