Given numbers are 856,824,847,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,824,847,560 is 746782960.
Find LCM of 856,824,847,560 with Prime Factorization
| 2 | 856, 824, 847, 560 |
| 2 | 428, 412, 847, 280 |
| 2 | 214, 206, 847, 140 |
| 7 | 107, 103, 847, 70 |
| 107, 103, 121, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 107 x 103 x 121 x 10 = 746782960
Therefore, the lowest common multiple of 856,824,847,560 is 746782960.
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.
856 x 824 x 847 x 560 = 334558766080
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
824 : 1, 2, 4, 8, 103, 206, 412, 824
847 : 1, 7, 11, 77, 121, 847
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,824,847,560, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
824:2x 2x 2x 103
847:7x 11x 11
560:2x 2x 2x 2x 5x 7
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 7 = 448
Therefore, the value for common factors is 448.
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 = 334558766080/(1x448)
LCM = 334558766080/448
LCM = 746782960
Thus, we can understand that the LCM of 856,824,847,560 is 746782960.
