Given numbers are 130,643,688,977,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,643,688,977,860 is 28093595920.
Find LCM of 130,643,688,977,860 with Prime Factorization
| 2 | 130, 643, 688, 977, 860 |
| 2 | 65, 643, 344, 977, 430 |
| 5 | 65, 643, 172, 977, 215 |
| 43 | 13, 643, 172, 977, 43 |
| 13, 643, 4, 977, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 13 x 643 x 4 x 977 x 1 = 28093595920
Therefore, the lowest common multiple of 130,643,688,977,860 is 28093595920.
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.
130 x 643 x 688 x 977 x 860 = 48320984982400
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
643 : 1, 643
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
977 : 1, 977
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,643,688,977,860, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
643:643
688:2x 2x 2x 2x 43
977:977
860:2x 2x 5x 43
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 5x 43 = 1720
Therefore, the value for common factors is 1720.
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 = 48320984982400/(1x1720)
LCM = 48320984982400/1720
LCM = 28093595920
Thus, we can understand that the LCM of 130,643,688,977,860 is 28093595920.
