The LCM is: 25
All factors of 25 and 4 are lowest common multiples of some numbers. Factors of 25: 1, 5, 25 Factors of 4: 1, 2, 4 eg 25 is lcm of 5 and 25. The only (and thus) lowest common factor of 25 and 4 is 1. Thus the lowest common multiple of 25 and 4 is 100.
30
The lowest common multiple is 60.
10, (lowest number that is divisible by 2 and 5).
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
35 7x5
The LCM is 30.
The Lowest Common Multiple (LCM) of 3 and 10 would be 30
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
The lowest multiple of any number is the number itself. The lowest common multiple of 4 and 5 is 20.
50 is one.
