The smallest number that can divide 40, 50, 75, and 90.

List all factors of each. 40 = 1, 2, 5, 8, 20, 40

50 = 1, 2, 5, 10, 25, 50

75 = 1, 3, 5, 15, 25, 75

90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

**The smallest number that can divide into 40, 50, 75 and 90 is 5.**

Smallest number divisible by 36, 18, 27.

List multiples of each: 36 = 36, 72, 108, 144, ...

18 = 18, 36, 54, 72, 90, 108, ...

27 = 27, 54, 81, 108

**Smallest number divisible by 36, 18, 27 is 108.**

Smallest number divisible by 30, 40, and 50

Prme factorization of each: 30 = `2*3*5`

40 = `2^3*5`

50 = `2*5^2`

**Smallest number divisble by 30, 40, and 50 would be `2^3*3*5^2` or 600.**
