Given numbers are 157,511,396,806,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,511,396,806,774 is 550540458468.
Find LCM of 157,511,396,806,774 with Prime Factorization
| 2 | 157, 511, 396, 806, 774 |
| 3 | 157, 511, 198, 403, 387 |
| 3 | 157, 511, 66, 403, 129 |
| 157, 511, 22, 403, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 157 x 511 x 22 x 403 x 43 = 550540458468
Therefore, the lowest common multiple of 157,511,396,806,774 is 550540458468.
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.
157 x 511 x 396 x 806 x 774 = 19819456504848
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.
157 : 1, 157
511 : 1, 7, 73, 511
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
806 : 1, 2, 13, 26, 31, 62, 403, 806
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,511,396,806,774, is 1.
Now, the common factors can be found like this.
157:157
511:7x 73
396:2x 2x 3x 3x 11
806:2x 13x 31
774:2x 3x 3x 43
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 3 = 36
Therefore, the value for common factors is 36.
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 = 19819456504848/(1x36)
LCM = 19819456504848/36
LCM = 550540458468
Thus, we can understand that the LCM of 157,511,396,806,774 is 550540458468.
