18 and 9 * * * * * Not so. LCM(9, 18) = 18, not 54. The correct answer is 18, 27.
A set of numbers can only have one GCF. 6, 12 and 18 have a GCF of 6. 16, 32 and 48 have a GCF of 16. 25, 50 and 75 have a GCF of 25. The GCF of 6, 16 and 25 is 1.
The numbers are 18 and 20.
The GCF of the given numbers is 18
31 and 18
18, 36 and 54
18, 36, 54
You need at least two numbers to find a GCF. The GCF of 18 and 24 is 6.
18, 1800, 18000
18 and 81
They could be 12 and 18
You need at least two numbers to find a GCF.
18 36 and the last one 54
126 and 90 (trial and error gets you the answer)
You need at least two numbers to find a GCF.
18 and 9 * * * * * Not so. LCM(9, 18) = 18, not 54. The correct answer is 18, 27.
You need at least two numbers to find a GCF. If that's 18 and 35, the GCF is 1.
