Given numbers are 851,854,391,938,896
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,854,391,938,896 is 52977459584.
Find LCM of 851,854,391,938,896 with Prime Factorization
| 2 | 851, 854, 391, 938, 896 |
| 7 | 851, 427, 391, 469, 448 |
| 23 | 851, 61, 391, 67, 64 |
| 37, 61, 17, 67, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 37 x 61 x 17 x 67 x 64 = 52977459584
Therefore, the lowest common multiple of 851,854,391,938,896 is 52977459584.
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.
851 x 854 x 391 x 938 x 896 = 238822387804672
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.
851 : 1, 23, 37, 851
854 : 1, 2, 7, 14, 61, 122, 427, 854
391 : 1, 17, 23, 391
938 : 1, 2, 7, 14, 67, 134, 469, 938
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,854,391,938,896, is 1.
Now, the common factors can be found like this.
851:23x 37
854:2x 7x 61
391:17x 23
938:2x 7x 67
896:2x 2x 2x 2x 2x 2x 2x 7
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 7x 7x 23 = 4508
Therefore, the value for common factors is 4508.
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 = 238822387804672/(1x4508)
LCM = 238822387804672/4508
LCM = 52977459584
Thus, we can understand that the LCM of 851,854,391,938,896 is 52977459584.
