Given numbers are 391,780,930,753,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,780,930,753,107 is 253916283660.
Find LCM of 391,780,930,753,107 with Prime Factorization
| 2 | 391, 780, 930, 753, 107 |
| 3 | 391, 390, 465, 753, 107 |
| 5 | 391, 130, 155, 251, 107 |
| 391, 26, 31, 251, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 391 x 26 x 31 x 251 x 107 = 253916283660
Therefore, the lowest common multiple of 391,780,930,753,107 is 253916283660.
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.
391 x 780 x 930 x 753 x 107 = 22852465529400
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.
391 : 1, 17, 23, 391
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
753 : 1, 3, 251, 753
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,780,930,753,107, is 1.
Now, the common factors can be found like this.
391:17x 23
780:2x 2x 3x 5x 13
930:2x 3x 5x 31
753:3x 251
107:107
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 22852465529400/(1x90)
LCM = 22852465529400/90
LCM = 253916283660
Thus, we can understand that the LCM of 391,780,930,753,107 is 253916283660.
