Given numbers are 681,320,906,703,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,320,906,703,515 is 2382684761280.
Find LCM of 681,320,906,703,515 with Prime Factorization
| 2 | 681, 320, 906, 703, 515 |
| 3 | 681, 160, 453, 703, 515 |
| 5 | 227, 160, 151, 703, 515 |
| 227, 32, 151, 703, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 227 x 32 x 151 x 703 x 103 = 2382684761280
Therefore, the lowest common multiple of 681,320,906,703,515 is 2382684761280.
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.
681 x 320 x 906 x 703 x 515 = 71480542838400
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.
681 : 1, 3, 227, 681
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
906 : 1, 2, 3, 6, 151, 302, 453, 906
703 : 1, 19, 37, 703
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,320,906,703,515, is 1.
Now, the common factors can be found like this.
681:3x 227
320:2x 2x 2x 2x 2x 2x 5
906:2x 3x 151
703:19x 37
515:5x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 71480542838400/(1x30)
LCM = 71480542838400/30
LCM = 2382684761280
Thus, we can understand that the LCM of 681,320,906,703,515 is 2382684761280.
