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 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.
The two whole numbers that go into 40 evenly are 1, 2, 4, 5, 8, 10, 20, and 40.
((1 + 40) x 20)/40 ie 20.5
