The sum of five continuous natural numbers is 50. Find the least common multiple of these five natural numbers

The sum of five continuous natural numbers is 50. Find the least common multiple of these five natural numbers

If the sum of five consecutive natural numbers is 50, their average is 50 / 5 = 10
These five numbers are 8, 9, 10, 11 and 12
8=2*2*2
9=3*3
10=2*5
11=11
12=2*2*3
Find their least common multiple
The result is 2 * 2 * 2 * 3 * 3 * 5 * 11 = 3960

If a = 11111, B = 11111, C = 111111, then the largest of a, B, C is______ The smallest is______ ．

The reciprocal of 11111 is 11111 = 101111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111

A and B are prime numbers. A * B is less than 100 and is a factor of 30. If a + B is even, what are a and B?

30: 1, 30, 2, 15, 3, 10, 5, 6
A and B are prime numbers. A * B is less than 100 and is a factor of 30. A + B is even, so a and B are 3 and 5
