How about 40 and 1.
1,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39 are the composite numbers between 1 and 40.
4, 9, 16, 25, and 36 are the square numbers between 1 and 40.

tere are an infinite number of numbers that divide into 40 i.e. 0.00000000etc 1 to 39.00000000etc to 40
320 As 8:1 is 7 different (8-1) then divide 280/7 to get 40 Then 40+280 = 320 and 320/40 = 8 so is still 8:1 ratio.
The sum of the numbers 1 to 39 = 39 x 40 ÷ 2 = 780 The sum of the numbers 1 to 60 = 60 x 61 ÷ 2 = 1830 Therefore the sum of the numbers 40 to 60 = 1830 - 780 = 1050
1, 4, 9, 16, 25, 36. These are the perfect squares from 1 to 40.
The GCF is 1.
The two whole numbers that go into 40 evenly are 1, 2, 4, 5, 8, 10, 20, and 40.
The numbers that go into 38 are its divisors: 1, 2, 19, and 38. For 40, the divisors are 1, 2, 4, 5, 8, 10, 20, and 40. Both numbers share some common divisors, specifically 1 and 2.
((1 + 40) x 20)/40 ie 20.5
