Given numbers are 476,856,781,621,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,856,781,621,418 is 938678695416.
Find LCM of 476,856,781,621,418 with Prime Factorization
| 2 | 476, 856, 781, 621, 418 |
| 2 | 238, 428, 781, 621, 209 |
| 11 | 119, 214, 781, 621, 209 |
| 119, 214, 71, 621, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 119 x 214 x 71 x 621 x 19 = 938678695416
Therefore, the lowest common multiple of 476,856,781,621,418 is 938678695416.
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.
476 x 856 x 781 x 621 x 418 = 82603725196608
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
856 : 1, 2, 4, 8, 107, 214, 428, 856
781 : 1, 11, 71, 781
621 : 1, 3, 9, 23, 27, 69, 207, 621
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,856,781,621,418, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
856:2x 2x 2x 107
781:11x 71
621:3x 3x 3x 23
418:2x 11x 19
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 11 = 88
Therefore, the value for common factors is 88.
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 = 82603725196608/(1x88)
LCM = 82603725196608/88
LCM = 938678695416
Thus, we can understand that the LCM of 476,856,781,621,418 is 938678695416.
