Given numbers are 557,660,625,690,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,660,625,690,343 is 362519272500.
Find LCM of 557,660,625,690,343 with Prime Factorization
| 2 | 557, 660, 625, 690, 343 |
| 3 | 557, 330, 625, 345, 343 |
| 5 | 557, 110, 625, 115, 343 |
| 557, 22, 125, 23, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 557 x 22 x 125 x 23 x 343 = 362519272500
Therefore, the lowest common multiple of 557,660,625,690,343 is 362519272500.
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.
557 x 660 x 625 x 690 x 343 = 54377890875000
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.
557 : 1, 557
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
625 : 1, 5, 25, 125, 625
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,660,625,690,343, is 1.
Now, the common factors can be found like this.
557:557
660:2x 2x 3x 5x 11
625:5x 5x 5x 5
690:2x 3x 5x 23
343:7x 7x 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 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 54377890875000/(1x150)
LCM = 54377890875000/150
LCM = 362519272500
Thus, we can understand that the LCM of 557,660,625,690,343 is 362519272500.
