Given numbers are 515,755,947,207
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,755,947,207 is 15244195185.
Find LCM of 515,755,947,207 with Prime Factorization
| 5 | 515, 755, 947, 207 |
| 103, 151, 947, 207 |
Multiply the prime numbers at the bottom and the left side.
5 x 103 x 151 x 947 x 207 = 15244195185
Therefore, the lowest common multiple of 515,755,947,207 is 15244195185.
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.
515 x 755 x 947 x 207 = 76220975925
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.
515 : 1, 5, 103, 515
755 : 1, 5, 151, 755
947 : 1, 947
207 : 1, 3, 9, 23, 69, 207
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,755,947,207, is 1.
Now, the common factors can be found like this.
515:5x 103
755:5x 151
947:947
207:3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 76220975925/(1x5)
LCM = 76220975925/5
LCM = 15244195185
Thus, we can understand that the LCM of 515,755,947,207 is 15244195185.
