Given numbers are 515,972,915,480
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,972,915,480 is 244283040.
Find LCM of 515,972,915,480 with Prime Factorization
| 2 | 515, 972, 915, 480 |
| 2 | 515, 486, 915, 240 |
| 3 | 515, 243, 915, 120 |
| 5 | 515, 81, 305, 40 |
| 103, 81, 61, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 103 x 81 x 61 x 8 = 244283040
Therefore, the lowest common multiple of 515,972,915,480 is 244283040.
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 972 x 915 x 480 = 219854736000
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
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
915 : 1, 3, 5, 15, 61, 183, 305, 915
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,972,915,480, is 1.
Now, the common factors can be found like this.
515:5x 103
972:2x 2x 3x 3x 3x 3x 3
915:3x 5x 61
480:2x 2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 219854736000/(1x900)
LCM = 219854736000/900
LCM = 244283040
Thus, we can understand that the LCM of 515,972,915,480 is 244283040.
