Given numbers are 713,248,856,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 713,248,856,720 is 54929520.
Find LCM of 713,248,856,720 with Prime Factorization
| 2 | 713, 248, 856, 720 |
| 2 | 713, 124, 428, 360 |
| 2 | 713, 62, 214, 180 |
| 31 | 713, 31, 107, 90 |
| 23, 1, 107, 90 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 23 x 1 x 107 x 90 = 54929520
Therefore, the lowest common multiple of 713,248,856,720 is 54929520.
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.
713 x 248 x 856 x 720 = 108980167680
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.
713 : 1, 23, 31, 713
248 : 1, 2, 4, 8, 31, 62, 124, 248
856 : 1, 2, 4, 8, 107, 214, 428, 856
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,248,856,720, is 1.
Now, the common factors can be found like this.
713:23x 31
248:2x 2x 2x 31
856:2x 2x 2x 107
720:2x 2x 2x 2x 3x 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 2x 2x 2x 2x 31 = 1984
Therefore, the value for common factors is 1984.
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 = 108980167680/(1x1984)
LCM = 108980167680/1984
LCM = 54929520
Thus, we can understand that the LCM of 713,248,856,720 is 54929520.
