2 numbers have the LCM of 30 and an HCF of 3 what are the numbers?

HCF of 3 means that the two numbers share 3 as a prime factor. LCM of 30 means there is a 2, a 3 and a 5 as prime factors between the numbers.
With this info, we can have the combination where one number has a 2 and the other a 5 (and both have the 3) or one number has just the 3 and the other has 2, 3 and 5.
Thus the 2 numbers can be 6 and 15. Or they can be 3 and 30.

What 2 numbers have the LCM of 30 and the HCF of 3?
3 and 30.
Two numbers have the LCM of 20 and a HCF of 2 What are they?
2 and 20
What 2 numbers have an LCM of 54 and an HCF of 3?
They are 9 and 6
If 13 is HCF of 2 number whose product is 1690 find the LCM?
To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.
What is the two numbers whose LCM is 30 and the gcf is 2?
2 and 30 6 and 10
What 2 numbers have the LCM of 30 and the HCF of 3?
3 and 30.
Which 2 numbers have a HCF of 2 and a LCM of 30?
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
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 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 hcf and LCM of 14 and 30?
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
What two numbers have the LCM of 30 and a HCF of 1?

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 .
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
Two numbers have an LCM of 12 an HCF of 2 what are they?
2 and 12
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.
