Answer:
The LCM of 40 and 5 is simply 40.
Step-by-step explanation:
To find the lowest common multiple of any 2 numbers, we will first list the prime factors of each number.
40: 2 × 2 × 2 × 5
5: 5
Then we need to multiply each factor the most amount of times it appears in either number.
2: 3 times in the first number
5: 1 time in either number
Now we multiply these.
2 × 2 × 2 × 5 = 40
The LCM of 40 and 5 is simply 40.
