It is: 9
The GCF is 9.
The Greatest Common Divisor of 81, 132 is 3.
The Greatest Common Divisor is 1
The Greatest Common Divisor of two numbers is the largest number that will divide into both evenly. For example, although 27 and 81 are both divisible by 3, it wouldn't be the greatest common divisor, because 27 divides into 81 evenly as well: the greatest common divisor of 27 and 81 is 27.
Greatest Common Divisor (GCF) for 81 16 is 1.
The GCF is 9.
well 18: 2 times 3 times 3 and 63: 3 times 3 times 7 and 117:3 times 3 times 13 the number tat ocurs the most is :3 and 3 so u multiply 3 times 3 = 9 so the GCD IS 9! hope this helps and byee done by: Paven Samrai
Factors of 63: 1, 3, 7, 9, 21 and 63.Factors of 81: 1, 3, 9, 27 and 81.Common factors are 1, 3 and 9.And another method is by finding the GCF of 63 and 81.The factors of GCF are the common factors of 63 and 81.GCF of 63 and 81 is 9. And factors of 9 are 1, 3 and 9.Instead of writing all factors of 63 and 81 it is better to find GCF and then its factors.
Nine 7x9=63 so 63/9=7 9x9=81 s0 81/9=9
The Least Common Multiple (LCM) for 81 36 63 is 2,268.
The highest common factor of 81 and 63 is 9
