The smallest positive integer that will divide exactly into all the numbers in any set of numbers is 1. The largest integer that will divide exactly into 567 and 8 is also 1 - this is their Highest Common Factor. The smallest integer that 567 and 8 will both divide into is 4536 - this is their Lowest Common Multiple.
345 is an odd number. This is because odd numbers don't divide by 2 exactly, but even numbers do divide by 2 exactly. 345 divided by 2 is 172.5 which is not a whole number. Therefore 345 is an odd number.
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
The number halfway between 40 and 60 is the average of the two numbers. To find the average, you add the two numbers together and divide by 2. In this case, (40 + 60) / 2 = 50. Therefore, 50 is the number that is halfway between 40 and 60.
12 and any multiple of it like 24, 36, 48, 60 etc
all numbers that can divide 60 are the factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60
60
2 and 60 will divide evenly into 120.
Divide 60 by the first six counting numbers.
Since 17 is a prime number - the only two numbers that will divide into it exactly are 1 & 17 !
3, 5, 11
30
30, 20 and 12
The prime numbers required are 2, 3, 5 and 7
