To find the HCF of two numbers, you first have to express them as the product of their prime factors. In this case we have: 6 = 2x3 90 = 2x3x3x5 The next step is to identify any common factors. In this case both numbers have a 2 and a 3 as a prime factor. Multiply these and you get 6. Thus the HCF of 6 and 90 is 6.
The HCF of 28 and 90 is 2

The GCF is 6.
To find the HCF of two numbers, you first have to express them as the product of their prime factors. In this case we have: 6 = 2x3 90 = 2x3x3x5 The next step is to identify any common factors. In this case both numbers have a 2 and a 3 as a prime factor. Multiply these and you get 6. Thus the HCF of 6 and 90 is 6.
Each HCF has its own set of prime factors.
The HCF of 4 and 90 is 2.
The GCF is 18.
The GCF is 30.
66, 90, & 115 Reduce each number to its prime factors. Hence 66 = 11,3,2 90 = 18,6 = 3,6,6 = 3,3,3,2,2 115 = 5,23 The HCF between 66, & 90 is 3,2 = 6 There is no common factor between 115 and 66,90.
HCF(160, 90) = 10.
Factors of 24: 1,2,3,4,6,8,12 and 24. Factors of 90: 1,2,3,5,9,10,18,30,45 and 90. The HCF (highest common factor) is 3.
To find the HCF you first need to break the numbers down into their prime factors. In this case we have: 30 = 2x3x5 45 = 3x3x5 The next step is to identify any common factors. In this case both numbers have 3 and 5 as prime factors. To find the HCF, multiply these together: 3x5 = 15. To get the LCM, multiply the numbers together then divide by the HCF: 30x45/15 = 90.
The hcf is 15.
