Given numbers are 417,705,987,678,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,705,987,678,354 is 9146657310.
Find LCM of 417,705,987,678,354 with Prime Factorization
| 2 | 417, 705, 987, 678, 354 |
| 3 | 417, 705, 987, 339, 177 |
| 47 | 139, 235, 329, 113, 59 |
| 139, 5, 7, 113, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 47 x 139 x 5 x 7 x 113 x 59 = 9146657310
Therefore, the lowest common multiple of 417,705,987,678,354 is 9146657310.
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.
417 x 705 x 987 x 678 x 354 = 69642648758340
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.
417 : 1, 3, 139, 417
705 : 1, 3, 5, 15, 47, 141, 235, 705
987 : 1, 3, 7, 21, 47, 141, 329, 987
678 : 1, 2, 3, 6, 113, 226, 339, 678
354 : 1, 2, 3, 6, 59, 118, 177, 354
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,705,987,678,354, is 3.
Now, the common factors can be found like this.
417:3x 139
705:3x 5x 47
987:3x 7x 47
678:2x 3x 113
354:2x 3x 59
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 3x 3x 47 = 2538
Therefore, the value for common factors is 2538.
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 = 69642648758340/(3x2538)
LCM = 69642648758340/7614
LCM = 9146657310
Thus, we can understand that the LCM of 417,705,987,678,354 is 9146657310.
