What two numbers have the LCM of 30 and a HCF of 1?
2 and 15 3 and 10 5 and 6
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
What is the HCF of 6 12 and 15?
3
What is the HCF of 6 and 15?
Well darling, the Highest Common Factor (HCF) of 6 and 15 is 3. It's like finding the hottest person in a room full of average Joes - they stand out because they're the biggest factor that both numbers share. So, there you have it, 3 is the HCF of 6 and 15.
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 of 30 and 40?
10
Which 2 numbers have a HCF of 2 and a LCM of 30?
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
What will go onto 6 and 15?
The HCF is 3
What is the hcf of 10 amd 15?

Hcf of 10 and 15?
The GCF is 5.
Hcf of 6 and 10?
The GCF is 2.
What is the HCF of 6 and 10?
2 6= 2,3 10= 2,5 2 Is the highest
