Two numbers have the LCM of 20 and a HCF of 2 What are they?
2 and 20
What is the HCF and LCM of 405 and 140?
2 x 2 x 5 x 7 = 140 5 x 9 x 9 = 405 HCF is 5 LCM is 11,340
What 2 numbers have the LCM of 30 and the HCF of 3?
3 and 30.
Highest common factor of 34 and 58?
The HCF is 2 The LCM is 986
What 2 numbers have an LCM of 54 and an HCF of 3?
They are 9 and 6
Why is the LCM of 12 and 13 the same as there product but the LCM of 12 and 14 is not the same as there product?
The LCM is the product of the two numbers divided by their HCF. With 12 and 13, the HCF is 1. Therefore, the LCM will equal the product. With 12 and 14, the HCF is 2. Therefore, the LCM will be half of the product.
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.
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 .
If LCM and HCF is known of 2 number along with 1 number can you find second number?
Yes: product of a & b = LCM x HCF so b = (LCM x HCF)/a
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 is the LCM of 64 and 610?
LCM of two numbers = their product divided by their HCF. The HCF of 64 and 610 is only 2 so the LCM is 64 x 610/2 ie 19520.
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 is the HCF of 2 prime nos?
The GCF of two prime numbers is 1.
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
What is the lcd of 2 and 8?
the LCM is 8. the hcf is 2
Two numbers have an LCM of 12 an HCF of 2 what are they?
2 and 12
