Given numbers are 726,620,245,560,409
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 726,620,245,560,409 is 18041709840.
Find LCM of 726,620,245,560,409 with Prime Factorization
| 2 | 726, 620, 245, 560, 409 |
| 2 | 363, 310, 245, 280, 409 |
| 5 | 363, 155, 245, 140, 409 |
| 7 | 363, 31, 49, 28, 409 |
| 363, 31, 7, 4, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 363 x 31 x 7 x 4 x 409 = 18041709840
Therefore, the lowest common multiple of 726,620,245,560,409 is 18041709840.
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.
726 x 620 x 245 x 560 x 409 = 25258393776000
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
245 : 1, 5, 7, 35, 49, 245
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,620,245,560,409, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
620:2x 2x 5x 31
245:5x 7x 7
560:2x 2x 2x 2x 5x 7
409:409
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 5x 7 = 1400
Therefore, the value for common factors is 1400.
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 = 25258393776000/(1x1400)
LCM = 25258393776000/1400
LCM = 18041709840
Thus, we can understand that the LCM of 726,620,245,560,409 is 18041709840.
