What number goes into 5 7 and 8?
The HCF of the given numbers is 1
What is the HCF of 42 and 35?
The HCF is 7.
What is the HCF of 16x27x49 and 8x27x125?
hcf(16×27×49, 8×2725) = 8×27 = 216 Using prime factorisation: 16×27×49 = 2⁴ × 3³ × 7² 8×27×125 = 2³ × 3³ × 5³ → hcf = 2³ × 3³ = 8×27 = 216
How do you simplify fractions such as 8 over 10?
The one-step method is to find the highest common denominator HCF of the numerator (top) and denominator (bottom) of the fraction and divide both of them by the HCF. If you don't know how to find the HCF just find any number that divides both the numerator and the denominator and divide both by that number. Then repeat and keep repeating until there is no number (other than 1 ) that divides both. So 8/10 HCF(8, 10) = 2 Therefore, simplified 8/10 = 8/2 divided by 10/2 = 4/5
What are the HCF of 45 9 and 8?
The HCF is 1.
