You need at least two numbers to find a GCF.
The GCF is 3.
-- The common factors of 3, 15, and 9 are 1 and 3 . -- Their greatest common factor is 3 . -- When discussing numbers, there is no such thing as the 'most' common factor.
the LCM of (a) and (b) is (ab) divided by (gcf of a and b) In this case, (a)=9 (45) = (9x)/(1) 45 = 9x 5= x ◄
You need at least two numbers to find a GCF. If that's 9 and 15, the GCF is 3.
9, 12, and 15 have the gcf of 3. 9: 1,3,9 12: 1,2,3,4,6,12 15: 1,3,5,15
The GCF of 9, 12, 15 is 3.
The GCF is 3.
The GCF is 3.
The same as what? The GCF of two numbers will be the same; the GCF of 3 and 9 will always be 3. The GCF of 9 and 12 will also always be 3, but the GCF of 4 and 12 will always be 4.
You need at least two numbers to find a GCF.
The common factors of 9, 12, and 15 are 1 and 3. The GCF is 3.
The GCF is 3.
3 and any multiple of 3. (For instance, 6, 9, 12, 15, etc.) Any multiples of 3 that differ by 3.
The GCF for the two numbers is 3 The factors of 9 are 3 and 3 The factors of 15 are 3 and 5 (9 does not share 5 with 15 as a factor and 3 only appears once as a factor for 15 so you can't use it a second time to increase the size of the GCF)
3 and 45 9 and 15
The GCF of 9 and 12 is 3
