Given numbers are 528,913,418,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 528,913,418,742 is 308915376.
Find LCM of 528,913,418,742 with Prime Factorization
| 2 | 528, 913, 418, 742 |
| 11 | 264, 913, 209, 371 |
| 24, 83, 19, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 24 x 83 x 19 x 371 = 308915376
Therefore, the lowest common multiple of 528,913,418,742 is 308915376.
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.
528 x 913 x 418 x 742 = 149515041984
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.
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
913 : 1, 11, 83, 913
418 : 1, 2, 11, 19, 22, 38, 209, 418
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 528,913,418,742, is 1.
Now, the common factors can be found like this.
528:2x 2x 2x 2x 3x 11
913:11x 83
418:2x 11x 19
742:2x 7x 53
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 149515041984/(1x484)
LCM = 149515041984/484
LCM = 308915376
Thus, we can understand that the LCM of 528,913,418,742 is 308915376.
