The hcf of 15 and 20 is 5
Both 15 and 20 can go into 60, as they are both factors of that number.
The only common factor of 15, 20 and 24 is 1.
15/5=3 100/5=20
The GCF of 15 and 20 is 5
The highest number that goes into both 5 and 20 is 5, which is their greatest common divisor (GCD). The GCD is the largest positive integer that divides both numbers without leaving a remainder. In this case, since 5 is a factor of 20, it is the highest number that meets the criteria.

The number of kids who have both dogs and cats can be calculated by adding the number of kids with dogs (20) to the number of kids with cats (15), then subtracting the total number of kids (29) from that sum. Therefore, 6 kids have both dogs and cats.

'15' Hence 3 x 5 = 15 or 15/3 = 5 or 15/5 = 3
The smallest number that 8 or 12 or 20 will all go in to is 120 120 = 20 x 6 = 12 x 10 = 8 x 15 as there is then no number that goes into 6 and 10 and 15 equally.
