-15
They are 20, 40, 60, 80, 100.
The multiples of 5 that are also multiples of 6 are multiples of their LCM. The LCM of 5 and 6 is 30, so the question becomes which multiples of 30 are less than 100? The solution is the numbers: 30, 60, 90
20
1 ÷ 5 = 0 r 1 → first multiple of 5 in the range 1-100 is 1 x 5 = 5 100 ÷ 5 = 20 → last multiples of 5 in the range 1-100 is 20 x 5 = 100 → want the first 20 multiples of 5, namely: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100.
20,40,60,80,and 100
-15
The first 5 multiples of 4 and 20 are 20, 40, 60, 80, 100
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.
They are: 25 50 75 100 and 125
They are 20, 40, 60, 80, 100.
2100, 4200, 6300, 8400, 10500.
The multiples of 5 that are also multiples of 6 are multiples of their LCM. The LCM of 5 and 6 is 30, so the question becomes which multiples of 30 are less than 100? The solution is the numbers: 30, 60, 90
What are the first three common multiples of four and five
They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
20, 40, 60, 80, 100, 120 * * * * * These are the first six multiples!
They are the first six multiples of 15.
