Which one is NOT divisible by 9 234 345 or 567?
For each given number, add the digits. If the sum comes to nine, then it is divisible by '9'. 234 ; 2 + 3 + 4 = 9 So is dividble by '9' 345 ; 3 + 4 + 5 = 12 = 1 + 2 = 3 Not divisible by '9' 567 ; 5 + 6 + 7 = 18 = 1 + 8 = 9 so is divisible by '9'.
What is the greatest common factor of 123 and 234?
The greatest common factor of 123 and 234 is 3.123: the digits (1, 2, 3) add up to 6.234: the digits (2, 3, 4) add up to 9.So both 6 and 9 are divisible by three.More formally:The prime factors of 123 are 3 and 41, while the prime factors of 234 are 2, 3, 3, and 13. The intersection of [3, 41] and [2, 3, 3, 13] is [3], therefore the Greatest Common Factor (GCF) of 123 and 234 is 3.
How do you know whether a number is a multiple of another number?
You test by := All EVEN Numbers are divisible by '2' All numbers ending in '5' or ''0' are divisible by '5' All numbers whose digits add to '9' are divisible by '9'. e.g. 234 2+3+4 = 9 All numbers whose form is ' m(m+n)n ' e.g. 132 are divisible by '11'. This leaves only '3' and '7' to test by actual division.
Which is a prime number 234 OR 788 OR 123 OR 563?
The only even prime is 2, so neither 234 nor 788 is prime. Since 1+2+3=6 is divisible by 3, the divisibility test for 3 says 123 can not be prime. If one of the options must be prime, then we know it is 563. Just to check:563 is odd and not divisible by 3,5,7,11,13,17,19, or 23. Since it is not divisible by any primes less than its square root, we know that 563 is not divisible by any whole numbers other than itself and one and is hence prime.
