Given numbers are 5151,8742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 5151,8742 is 15010014.
Find LCM of 5151,8742 with Prime Factorization
| 3 | 5151, 8742 |
| 1717, 2914 |
Multiply the prime numbers at the bottom and the left side.
3 x 1717 x 2914 = 15010014
Therefore, the lowest common multiple of 5151,8742 is 15010014.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
5151 x 8742 = 45030042
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
5151 : 1, 3, 17, 51, 101, 303, 1717, 5151
8742 : 1, 2, 3, 6, 31, 47, 62, 93, 94, 141, 186, 282, 1457, 2914, 4371, 8742
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5151,8742, is 3.
Now, the common factors can be found like this.
5151:3x 17x 101
8742:2x 3x 31x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 45030042/(3x1)
LCM = 45030042/3
LCM = 15010014
Thus, we can understand that the LCM of 5151,8742 is 15010014.
