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 .
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.
What is the relation between HCF and LCM?
Since the product of two numbers is equal to the product of their GCF and LCM, the GCF of two numbers is equal to their product divided by their LCM and their LCM is equal to their product divided by their GCF.
Which two numbers have an LCM of twelve and an HCF of two?
4 and 6
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.

What 2 numbers have a LCM of 12 and a HCF of 2?
2 and 12
Two numbers have the LCM of 20 and a HCF of 2 What are they?
2 and 20

2 and 12
How do you get the least common multiple of 27 and 45?
LCM = product/HCF; the HCF of 27 and 45 is 9 so LCM is 27 x 45/9 ie 135.LCM is the smallest multiple of 2 numbers and can be found by factoring both numbers and multiplying the prime factors having the highest powers.Prime factors of 27 are 33Prime factors of 45 are 32 x 5LCM of 27 and 45 is 33x 5 = 135
What 2 numbers have LCM of 20 and HCF of 2?
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
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.
Which 2 numbers have a HCF of 2 and a LCM of 30?
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
