This was one of my homework question. The answer is 12 and 18. To do this-
12:24,36,48
18:36
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
40 and any of its factors.
which pair of numbers from 1 to 30 has the LCM OF 120
The LCM of 5 and 6 is 30.
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
9 and 12
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
1 and 36 4 and 9
3 and 36 9 and 12
36 and 72 8 and 9
3 and 36 9 and 12
35 and 36 are coprime (any pair of consecutive numbers must be). So lcm(35, 36) = 35*36 = 1260.
4 and 9
9 and 12
The LCM is never less than the greatest number in the set. The LCM of 4 and 9 is 36.
You would have to be a pair of numbers. 6 and 36 would work, as would 12 and 18.
