Given numbers are 611,838,638,749,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,838,638,749,930 is 56886692332470.
Find LCM of 611,838,638,749,930 with Prime Factorization
| 2 | 611, 838, 638, 749, 930 |
| 611, 419, 319, 749, 465 |
Multiply the prime numbers at the bottom and the left side.
2 x 611 x 419 x 319 x 749 x 465 = 56886692332470
Therefore, the lowest common multiple of 611,838,638,749,930 is 56886692332470.
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.
611 x 838 x 638 x 749 x 930 = 227546769329880
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.
611 : 1, 13, 47, 611
838 : 1, 2, 419, 838
638 : 1, 2, 11, 22, 29, 58, 319, 638
749 : 1, 7, 107, 749
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,838,638,749,930, is 1.
Now, the common factors can be found like this.
611:13x 47
838:2x 419
638:2x 11x 29
749:7x 107
930:2x 3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 227546769329880/(1x4)
LCM = 227546769329880/4
LCM = 56886692332470
Thus, we can understand that the LCM of 611,838,638,749,930 is 56886692332470.
