5.. divides into 5 and 10.
hcf(320, 560) = 80 320 = 26 x 5 560 = 24 x 5 x 7 hcf = 24 x 5 = 80
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.
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.
hcf(320, 560) = 80 320 = 26 x 5 560 = 24 x 5 x 7 hcf = 24 x 5 = 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.
