Given numbers are 357,417,671,861,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,417,671,861,918 is 24573210354.
Find LCM of 357,417,671,861,918 with Prime Factorization
| 3 | 357, 417, 671, 861, 918 |
| 7 | 119, 139, 671, 287, 306 |
| 17 | 17, 139, 671, 41, 306 |
| 1, 139, 671, 41, 18 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 17 x 1 x 139 x 671 x 41 x 18 = 24573210354
Therefore, the lowest common multiple of 357,417,671,861,918 is 24573210354.
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.
357 x 417 x 671 x 861 x 918 = 78953724867402
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
417 : 1, 3, 139, 417
671 : 1, 11, 61, 671
861 : 1, 3, 7, 21, 41, 123, 287, 861
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,417,671,861,918, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
417:3x 139
671:11x 61
861:3x 7x 41
918:2x 3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 17 = 3213
Therefore, the value for common factors is 3213.
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 = 78953724867402/(1x3213)
LCM = 78953724867402/3213
LCM = 24573210354
Thus, we can understand that the LCM of 357,417,671,861,918 is 24573210354.
