Given numbers are 913,306,556,490,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,306,556,490,561 is 19028435580.
Find LCM of 913,306,556,490,561 with Prime Factorization
| 2 | 913, 306, 556, 490, 561 |
| 3 | 913, 153, 278, 245, 561 |
| 11 | 913, 51, 278, 245, 187 |
| 17 | 83, 51, 278, 245, 17 |
| 83, 3, 278, 245, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 83 x 3 x 278 x 245 x 1 = 19028435580
Therefore, the lowest common multiple of 913,306,556,490,561 is 19028435580.
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.
913 x 306 x 556 x 490 x 561 = 42699809441520
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.
913 : 1, 11, 83, 913
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
556 : 1, 2, 4, 139, 278, 556
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,306,556,490,561, is 1.
Now, the common factors can be found like this.
913:11x 83
306:2x 3x 3x 17
556:2x 2x 139
490:2x 5x 7x 7
561:3x 11x 17
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 3x 11x 17 = 2244
Therefore, the value for common factors is 2244.
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 = 42699809441520/(1x2244)
LCM = 42699809441520/2244
LCM = 19028435580
Thus, we can understand that the LCM of 913,306,556,490,561 is 19028435580.
