The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
The greatest common factor of 1200 and 1575 is 75
The GCF of 1225 and 1575 is 175
It is: 42000
least common multiple of 175 and 45 is 1575.
LCM(45, 105, 75) = 1575.
The factor pairs of 1575 are 1 x 1575, 3 x 525, 5 x 315, 7 x 225, 9 x 175, 15 x 105, 21 x 75, 25 x 63, and 35 x 45.
Since 315 is a factor of 1575, it is automatically the GCF of this problem.
Since 35 is a factor of 1575, it is automatically the GCF.
105
The GCF of 1225 and 1575 is 175
It is: 42000
The GCF is 105.
To find the highest common factor (HCF) of 441 and 1575, we need to factorize both numbers. The prime factorization of 441 is 3^2 x 7^2, and the prime factorization of 1575 is 3^2 x 5^2 x 7. To find the HCF, we take the product of the common prime factors raised to the lowest power they appear in both factorizations, which is 3^2 x 7 = 63. Therefore, the highest common factor of 441 and 1575 is 63.
