The GCF of 9 and 21 is 3.
2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
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
By treating it as a positive number. Since negative numbers include the factors of their positive counterparts and all positive numbers are greater than all negative numbers, the GCF will always be positive. The GCFs of (3, 9), (3, -9), (-3, 9) and (-3, -9) are all the same: positive 3.
The GCF is 9.
The GCF of 9 and 21 is 3.
2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
9, 18 and 27
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.
The GCF of these numbers is 9. This leaves you with 27 and 3 respectively
6 and 9
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 highest common factor of 9 and 30 is 3.
The greatest common factor of the numbers 45 and 63 is 9.
3 numbers that have a GCF of 3 are 6, 9 and 12.
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 ◄
