25 and 50
The first 10 multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50.The first 10 multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, and 70.
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.
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 first 6 multiples of 7 are: 7, 14, 21, 28, 35, and 42.
Example: 5 and 7 List the multiples of 5. 5, 10, 15, 20, 25, 30, 35, 40... List the multiples of 7. 7, 14, 21, 28, 35, 42... The LCM is the first number that appears on both lists.
