What is the hcf and the LCM of 10 and 15?
5 and 30, respectively.
I need to know which pair of numbers in relatively prime 10 and 21 or 12 and 54 or 15 and 27 or 21 and 38?
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
How do you find the ratio of 405 and 660?
It is: 27 to 44 by dividing them by their hcf which is 15

Common factors of 27 35 and 30?
The factors of: 27: 1, 3, 9, 27 35: 1, 5, 7, 35 30: 1, 2, 3, 5, 6, 10, 15, 30 Common factors: cf(27, 35): 1 cf(27, 30): 1, 3 cf(35, 30): 1, 5 cf(27, 35, 30): 1 27 = 3^3 35 = 5 x 7 30 = 2 x 3 x 5 The common factors are the factors of their highest common factor: hcf(27, 35) = 1 → cf(27, 35): 1 hcf(27, 30) = 3 → cf(26, 30): 1, 3 hcf(35, 30) = 5 → cf(35, 30): 1, 5 hcf(27, 35, 30) = 1 → cf(27, 35, 30): 1
What is the HCF of 15 and 27?
The GCF is 3.
What is the HCF of 30 and 15 and 9?
3
What is the hcf of 15 30 48?
It is 3
What is the HCF of 30 45 75?
The GCF is 15.
What is the GCF of 14 30 27?
The GCF is 1.
What 2 pair of numbers whose LCM is less than the product of the 2 numbers?
Any two numbers that have a common factor greater than 1 will have a LCM less than their product, eg: LCM(10, 15) = 30 < 10 x 15 = 150 (since HCF(10, 15) = 5) LCM(6, 10) = 30 < 6 x 10 = 60 (since HCF(6, 10) = 2) LCM(18, 27) = 54 < 18 x 27 = 486 (since HCF(18, 27) = 9)
What is the hcf and the LCM of 10 and 15?
5 and 30, respectively.
