The GCF is 9.
The question does not make any sense at all because72 is not an odd number72 is not the largest factor of 720
9
First, let's list the factors of 72, although it may seem tedious, it might be useful until you get the hang of it.1, 2, 3, 4, 6, 12, 18, 24, 36, 72.*Please Note*: That you may skip the step above if you need to.Second, the largest factor of any number is extremely simple. It's always the number itself.Example: Find the largest factor of 1337.It's a no-brainer. The largest factor is undoubtedly 1337, the number itself.Similarly, the largest factor of 72 is...well... 72.
The highest common factor (HCF) of 45 and 72 is the largest number that divides both 45 and 72 without leaving a remainder. To find the HCF, you can use methods like prime factorization or the Euclidean algorithm. In this case, the prime factorization of 45 is 3 x 3 x 5 and the prime factorization of 72 is 2 x 2 x 2 x 3 x 3. The common factors between 45 and 72 are 3 and 9 (3 x 3), so the HCF of 45 and 72 is 9.
Prime factor each number. 18=2x3x3 45=3x3x5 72=2x2x2x3x3 Use each prime factor the number of times it was used the MOST in any one of the numbers. 2x2x2x3x3x5=360 The least common denominator of 18, 45, and 72 is 360.
The GCF of 45 72 and 108 is 9
Because 18 is the largest number that divides evenly into both 72 and 90.
The GCF is 9.
The greatest common factor of the numbers 27, 45 and 72 is 9.
Three.
The GCF of 36, 45, and 72 is 9.
3: 3x20=60 3x15=45 3x24=72
