15
225 and 15, respectively.
HCF = 15
To find the Highest Common Factor (HCF) of 45, 75, and 125, we need to first find the prime factors of each number. The prime factors of 45 are 3 x 3 x 5, the prime factors of 75 are 3 x 5 x 5, and the prime factors of 125 are 5 x 5 x 5. To find the HCF, we look for the common prime factors among all three numbers, which are 5. Therefore, the HCF of 45, 75, and 125 is 5.
The hcf of 45 and 40 is 5.
They are 1, 2, 3, 5, 6, 10, 15, 25, 45, 75, 150.
The GCF is 3.
The GCF is 75.
The GCF is 15.
The HCF is 1.
The GCF is 1.
gcf(75, 45, 90) = 15 Using prime factorization: 75 = 3 x 5² 45 = 3² x 5 90 = 2 x 3² x 5 hcf = 3 x 5 = 15
