Can two numbe215r have 20 as their HCF and 215 as their LCM?
No, 2 and 10 are factors of 20. The LCM of 2 and 10 is 10.
Which two numbers have an LCM of 18 and HCF of 3?
HCF of 3 means the numbers both have a prime factor of 3. LCM of 12 means that, between the numbers, there are factors of 2, 2 and 3. But these 2s cannot be shared, else the HCF would be greater. Therefore, the numbers will need to be 3 and 2x2x3, or 12.
What numbers do 14 and 4 go into evenly?
1, 2.
What are three pairs of numbers that have a LCM of 30 and a HCF of 1?
30 & 1. 15 & 2. 10 & 3.
What is the greatest common factor of 420 and 2646?

Two numbers have the LCM of 20 and a HCF of 2 What are they?
2 and 20
Can two numbers have 20 as HCF and 535 as LCM?
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
What two numbers have a LCM of 20 and HCF of 2?
The answer is 4 and 10.
How do you find sets of two numbers if HCF and LCM are known?
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
Can two numbe215r have 20 as their HCF and 215 as their LCM?
No, 2 and 10 are factors of 20. The LCM of 2 and 10 is 10.
If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
