Find LCM of 287,484,874,748,553 with Prime Factorization
| 2 | 287, 484, 874, 748, 553 |
| 2 | 287, 242, 437, 374, 553 |
| 7 | 287, 121, 437, 187, 553 |
| 11 | 41, 121, 437, 187, 79 |
| 41, 11, 437, 17, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 41 x 11 x 437 x 17 x 79 = 81523855028
Therefore, the lowest common multiple of 287,484,874,748,553 is 81523855028.
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.
287 x 484 x 874 x 748 x 553 = 50218694697248
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.
287 : 1, 7, 41, 287
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
874 : 1, 2, 19, 23, 38, 46, 437, 874
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,484,874,748,553, is 1.
Now, the common factors can be found like this.
287:7x 41
484:2x 2x 11x 11
874:2x 19x 23
748:2x 2x 11x 17
553:7x 79
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 2x 7x 11 = 616
Therefore, the value for common factors is 616.
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 = 50218694697248/(1x616)
LCM = 50218694697248/616
LCM = 81523855028
Thus, we can understand that the LCM of 287,484,874,748,553 is 81523855028.
