The highest common factor (HCF) of two numbers is the largest number that divides both of them without leaving a remainder. To find the HCF of 150 and 75, we can use the method of prime factorization. The prime factors of 150 are 2 x 3 x 5 x 5, and the prime factors of 75 are 3 x 5 x 5. By comparing the common prime factors, we see that the HCF of 150 and 75 is 3 x 5, which equals 15.
HCF(375, 150) = 75.
Their greatest common factor is 75.
To find the greatest common factor, or GCF, you must first identify the factors for each number.For 150, its factors are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150.For 225, its factors are 1, 3, 5, 9, 15, 25, 45, 75, and 225.75 is the highest (or greatest) factor they have in common, so the GCF for 150 and 225 is 75
They are 1, 2, 3, 5, 6, 10, 15, 25, 45, 75, 150.
To find the LCM of two numbers, you first split them into their prime factors: 30 = 2x3x5 75 = 3x5x5 Next you need to work out the HCF. Here, the HCF will be 3x5 = 15. Finally, you multiply the numbers together and divide by the HCF. 30x75/15 = 150. Therefore the LCM of 30 and 75 is 150.
It is 50
