Given numbers are 878,720,980,510
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,720,980,510 is 263294640.
Find LCM of 878,720,980,510 with Prime Factorization
| 2 | 878, 720, 980, 510 |
| 2 | 439, 360, 490, 255 |
| 3 | 439, 180, 245, 255 |
| 5 | 439, 60, 245, 85 |
| 439, 12, 49, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 439 x 12 x 49 x 17 = 263294640
Therefore, the lowest common multiple of 878,720,980,510 is 263294640.
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.
878 x 720 x 980 x 510 = 315953568000
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.
878 : 1, 2, 439, 878
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,720,980,510, is 2.
Now, the common factors can be found like this.
878:2x 439
720:2x 2x 2x 2x 3x 3x 5
980:2x 2x 5x 7x 7
510:2x 3x 5x 17
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 2x 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 315953568000/(2x600)
LCM = 315953568000/1200
LCM = 263294640
Thus, we can understand that the LCM of 878,720,980,510 is 263294640.
