The first four multiples of five: 5, 10, 15, 20
The first 3 multiples of 13 are: 13, 26, and 39.
The total number of integers that are multiples of 25 and 6 is infinite. The first few are these: 150, 300, 450, 600, 750, 900 . . .
25, 50, 75, 100, 125, 150, 175.
The first six multiples of 3 are 3, 6, 9, 12, 15, and 18.
975
75, 150, 225.
Three multiples of 3 and 25 are: 75, 150, 225.
75, 150, 225
Sum of first 25 multiples of 44+8+12....100taking 4 common4(1+2+3+4....+25) = 4*325 =1300
12, 24, and 36
25 and 50
The sum of the first 25 numbers is 25*26/2 = 325 So the sum of the first 25 multiples of 12 is 325*12 = 3900
The highest power of 25 that divides the product of the first 100 multiples of 5 is 50. This is because for each multiple of 25, we have an extra factor of 25. Since there are 4 multiples of 25 in the first 100 multiples of 5, we have a total of 50 factors of 25.
Multiply it by the 1st ten odd numbers: 1*25 = 25, 3*25 = 75, 5*25 = 125 .... etc
The first 50 multiples of 6 are the first fifty even multiples of 3.
2100, 4200, 6300, 8400
