5.. divides into 5 and 10.
35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
The GCF is 42.
The HCF of 165 and 210 is 15. The LCM is 2310.
5 (leaves you with 2, 4 and 7)
The HCF of the given numbers is 1
hcf is 1 and LCM is 35
It is: 1
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
5.. divides into 5 and 10.
HCF is the highest common factor of two or more numbers. HCF of 25 and 40 is 5.
The Highest Common Factor (HCF) of 320 and 560 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor. By repeating this process, you will eventually find that the HCF of 320 and 560 is 80.
35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
Prime factors of 210 are: 2, 3, 5 and 7 Prime factors of 385 are: 5,7 and 11 Common factors are: 5 and 7 and so 5*7 = 35 which is the hcf
The HCF is 1
hcf(490, 1750) = 70 Using factorisation: 490 = 2 x 5 x 7² 1750 = 2 x 5³ x 7 hcf = 2 x 5 x 7 = 70
The GCF is 42.
