The answer is 20C4 = 20*19*18*17/(4*3*2*1) = 4845
1,19,23,27,30 ( divided by ) 5= 20
There are many answers. Here is one: 58 and 20
You can just find the factors: 1x30 2x15 3x10 5x6 so that's 8 numbers
There are 8 out of 20 numbers that are prime, so 8/20, or 2/5.
Three sets
1,2,3,4,5,6,10,12,15,20,30,60
There are infinitely many whole numbers which are less than 20. Start with 19 and go back, beyond 0, to negative infinity.
The numbers 1-20 are on a dart board so there are twenty numbers.
Any of their multiples
35 times equally no numbers left over.
1, 2, 4, 5, and 10 can go into 20.
The HCF of 39 and 20 is 1
20 numbers
20 numbers
how many odd numbers is there between 20 and 158
A single number, 20, does not have a lowest common multiple! So there are no two numbers to go in.
