To find the greatest common factor (GCF) of 72, 90, and 144, we first need to find the prime factorization of each number. The prime factorization of 72 is 2^3 * 3^2, the prime factorization of 90 is 2 * 3^2 * 5, and the prime factorization of 144 is 2^4 * 3^2. The GCF is the product of the common prime factors raised to the smallest exponent they appear in any of the numbers, which in this case is 2^3 * 3^2, equal to 72.
The GCF of 72 and 144 is 72. Since 72 is a factor of 144, it is automatically the GCF.
The GCF is: 24
The GCF is 12.
GCF (72, 144, 180) = 36
The GCF of 72, 120, and 144 is 24.
The GCF is 72.
The GCF of 72 and 144 is 72. Since 72 is a factor of 144, it is automatically the GCF.
