Given numbers are 397,902,314,572,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,902,314,572,768 is 280654023936.
Find LCM of 397,902,314,572,768 with Prime Factorization
| 2 | 397, 902, 314, 572, 768 |
| 2 | 397, 451, 157, 286, 384 |
| 11 | 397, 451, 157, 143, 192 |
| 397, 41, 157, 13, 192 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 397 x 41 x 157 x 13 x 192 = 280654023936
Therefore, the lowest common multiple of 397,902,314,572,768 is 280654023936.
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.
397 x 902 x 314 x 572 x 768 = 49395108212736
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.
397 : 1, 397
902 : 1, 2, 11, 22, 41, 82, 451, 902
314 : 1, 2, 157, 314
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,902,314,572,768, is 1.
Now, the common factors can be found like this.
397:397
902:2x 11x 41
314:2x 157
572:2x 2x 11x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 49395108212736/(1x176)
LCM = 49395108212736/176
LCM = 280654023936
Thus, we can understand that the LCM of 397,902,314,572,768 is 280654023936.
