Given numbers are 381,806,817,213,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,806,817,213,994 is 124691963214.
Find LCM of 381,806,817,213,994 with Prime Factorization
2 | 381, 806, 817, 213, 994 |
3 | 381, 403, 817, 213, 497 |
71 | 127, 403, 817, 71, 497 |
127, 403, 817, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 127 x 403 x 817 x 1 x 7 = 124691963214
Therefore, the lowest common multiple of 381,806,817,213,994 is 124691963214.
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.
381 x 806 x 817 x 213 x 994 = 53118776329164
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.
381 : 1, 3, 127, 381
806 : 1, 2, 13, 26, 31, 62, 403, 806
817 : 1, 19, 43, 817
213 : 1, 3, 71, 213
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,806,817,213,994, is 1.
Now, the common factors can be found like this.
381:3x 127
806:2x 13x 31
817:19x 43
213:3x 71
994:2x 7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 71 = 426
Therefore, the value for common factors is 426.
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 = 53118776329164/(1x426)
LCM = 53118776329164/426
LCM = 124691963214
Thus, we can understand that the LCM of 381,806,817,213,994 is 124691963214.
