8, 12, 16 & 208 + 12 = 20
8, 16, 24, 32
The first 6 multiples of 4 are: 4, 8, 12, 16, 20, and 24.
Multiply 8 by the first four counting numbers. 8, 16, 24, 32
First Six Multiples of 8The first six multiples of 8 are: 8, 16, 24, 32, 40, and 48.
Sum of the first 15 positive integers is 15*(15+1)/2 = 120 Sum of the first 15 multiples of 8 is 8*120 = 960
Well, the multiples of 8 go "8, 16, 24...etc." The first four multiples of 8 over 20 are 24, 32, 40, and 48. i) 24 + 32 = 56 ii) 56 + 40 = 96 iii) 96 + 48 = 144 Therefore the sum is 144.
5 + 10+15+20=50 ans
2,4,6, and 8
4 + 8 + 12 = 24
8, 12, 16 & 208 + 12 = 20
Multiples of 8 include 8, 16, 24 and 32. For them to be common, they need to be compared to another set of multiples.
8, 16, 24, 32
answer is 88,176,264
