Given numbers are 748,638,813,611,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,638,813,611,403 is 334035823836.
Find LCM of 748,638,813,611,403 with Prime Factorization
| 2 | 748, 638, 813, 611, 403 |
| 11 | 374, 319, 813, 611, 403 |
| 13 | 34, 29, 813, 611, 403 |
| 34, 29, 813, 47, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 34 x 29 x 813 x 47 x 31 = 334035823836
Therefore, the lowest common multiple of 748,638,813,611,403 is 334035823836.
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.
748 x 638 x 813 x 611 x 403 = 95534245617096
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
638 : 1, 2, 11, 22, 29, 58, 319, 638
813 : 1, 3, 271, 813
611 : 1, 13, 47, 611
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,638,813,611,403, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
638:2x 11x 29
813:3x 271
611:13x 47
403:13x 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 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 95534245617096/(1x286)
LCM = 95534245617096/286
LCM = 334035823836
Thus, we can understand that the LCM of 748,638,813,611,403 is 334035823836.
