If there are only two numbers, then 6 and 8
2 and 24
6 and 8
2 and 12
2 and 12
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
In these types of problems, the numbers can also be the answer. 6 and 72 have a GCF of 6 and an LCM of 72. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 432, like 18 and 24.
2 and 12
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.
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 .
2 and 12
2 and 20
2 and 12
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
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.
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
2 and 12
The LCM of 54 and 24 is 216.The Least Common Multiple (LCM) for 54 24 is 216factoring24=2*2*2*354=2*3*3*3so LCM =2*2*2*3*3*3=216
In these types of problems, the numbers can also be the answer. 6 and 72 have a GCF of 6 and an LCM of 72. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 432, like 18 and 24.
How about 4 and 6
