Given numbers are 681,572,354,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,572,354,687 is 5262966852.
Find LCM of 681,572,354,687 with Prime Factorization
2 | 681, 572, 354, 687 |
3 | 681, 286, 177, 687 |
227, 286, 59, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 227 x 286 x 59 x 229 = 5262966852
Therefore, the lowest common multiple of 681,572,354,687 is 5262966852.
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.
681 x 572 x 354 x 687 = 94733403336
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.
681 : 1, 3, 227, 681
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
354 : 1, 2, 3, 6, 59, 118, 177, 354
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,572,354,687, is 1.
Now, the common factors can be found like this.
681:3x 227
572:2x 2x 11x 13
354:2x 3x 59
687:3x 229
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 3 = 18
Therefore, the value for common factors is 18.
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 = 94733403336/(1x18)
LCM = 94733403336/18
LCM = 5262966852
Thus, we can understand that the LCM of 681,572,354,687 is 5262966852.
