Given numbers are 818,770,858,467,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,770,858,467,639 is 1221729679170.
Find LCM of 818,770,858,467,639 with Prime Factorization
| 2 | 818, 770, 858, 467, 639 |
| 3 | 409, 385, 429, 467, 639 |
| 11 | 409, 385, 143, 467, 213 |
| 409, 35, 13, 467, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 409 x 35 x 13 x 467 x 213 = 1221729679170
Therefore, the lowest common multiple of 818,770,858,467,639 is 1221729679170.
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.
818 x 770 x 858 x 467 x 639 = 161268317650440
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.
818 : 1, 2, 409, 818
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
467 : 1, 467
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,770,858,467,639, is 1.
Now, the common factors can be found like this.
818:2x 409
770:2x 5x 7x 11
858:2x 3x 11x 13
467:467
639:3x 3x 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 2x 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 161268317650440/(1x132)
LCM = 161268317650440/132
LCM = 1221729679170
Thus, we can understand that the LCM of 818,770,858,467,639 is 1221729679170.
