1, 2, 5 and 10
1 or 2.
1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150.
HCF(30, 1000) = 10HCF(30, 1000) = 10HCF(30, 1000) = 10HCF(30, 1000) = 10
numbers are infinite so this question is impossible, but 30,60,90,120, and so forth go into 30 and 10 evenly.
30
1, 2, 5, 10.
Their GCF which is 2
1 or 2.
The numbers 1,2,3,5,6,10,15,and 30 go into 30 evenly.
How about 30
1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150.
HCF(30, 1000) = 10HCF(30, 1000) = 10HCF(30, 1000) = 10HCF(30, 1000) = 10
The GCF of those numbers is 10 because it is the largest number that goes into both of the other numbers evenly.
numbers are infinite so this question is impossible, but 30,60,90,120, and so forth go into 30 and 10 evenly.
30
1, 2, 3, 5, 6, 10, 15, 30.
Because 30 is the smallest number that both 10 and 15 can divide into evenly with no remainder.
