9.Why? Because 9 x 6 = 54, and 9 x 5 = 45. No number larger than 9 is both a factor of 54 AND 45.
9 is paired with 6 to give you 54. 9x6 is 54.
The greatest common factor of 54, 5, 36, and 45 is 1.
9
There are two prime factors of 45, they are 3 and 5. The prime factors of 54 are 2 and 3.
9 54/9 = 6 45/9 = 5
The GCF of 45 and 54 is 9. The GCF can't be greater than the difference between the numbers, which is 9 in this case. Since 9 is a factor of both 45 and 54, it is the GCF.
9.Why? Because 9 x 6 = 54, and 9 x 5 = 45. No number larger than 9 is both a factor of 54 AND 45.
54 is the greatest common factor of 54 and 108 since it is the largest common factor in both. 1*54 = 54 2 * 54 = 108
9 is the greatest common factor of 18, 45 and 54.
Factor both numbers into primes. Circle any common primes and multiply them/ 45=3x3x5 54=2x3x3x3 3x3=9 GCF
The Greatest Common Factor of 36, 45, 54: 9
54 is the largest factor of itself.
9 is paired with 6 to give you 54. 9x6 is 54.
The greatest common factor of 54, 5, 36, and 45 is 1.
9
Both 9 and 3 go into both numbers. 45/54 = 5/6 45/54 = 15/18
