Given numbers are 513,218,785,771,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,218,785,771,646 is 383553155610.
Find LCM of 513,218,785,771,646 with Prime Factorization
| 2 | 513, 218, 785, 771, 646 |
| 3 | 513, 109, 785, 771, 323 |
| 19 | 171, 109, 785, 257, 323 |
| 9, 109, 785, 257, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 9 x 109 x 785 x 257 x 17 = 383553155610
Therefore, the lowest common multiple of 513,218,785,771,646 is 383553155610.
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.
513 x 218 x 785 x 771 x 646 = 43725059739540
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
218 : 1, 2, 109, 218
785 : 1, 5, 157, 785
771 : 1, 3, 257, 771
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,218,785,771,646, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
218:2x 109
785:5x 157
771:3x 257
646:2x 17x 19
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 19 = 114
Therefore, the value for common factors is 114.
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 = 43725059739540/(1x114)
LCM = 43725059739540/114
LCM = 383553155610
Thus, we can understand that the LCM of 513,218,785,771,646 is 383553155610.
