Answer:
60
Explanation:
The highest common multiple or GCF of any two numbers is the largest factor that both numbers share. For instance,
The multiples of 12 are as follows:
1 and 12
3 and 4
2 and 6
The Multiples of 30 are as follows:
1 and 30
2 and 15
5 and 6
The factor that these two numbers share is 6, so therefore, your GCF is 6
To find the greatest common multiple, we need to know what number both 12 and 30 have in common which is 60 since:
30 can be multiplied by 2 to get 60
12 can be multplied by 5 to get 60
Hope this Helps!
