Given numbers are 654,759,987,799
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,759,987,799 is 925428966.
Find LCM of 654,759,987,799 with Prime Factorization
| 3 | 654, 759, 987, 799 |
| 47 | 218, 253, 329, 799 |
| 218, 253, 7, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 218 x 253 x 7 x 17 = 925428966
Therefore, the lowest common multiple of 654,759,987,799 is 925428966.
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.
654 x 759 x 987 x 799 = 391456452618
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
759 : 1, 3, 11, 23, 33, 69, 253, 759
987 : 1, 3, 7, 21, 47, 141, 329, 987
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,759,987,799, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
759:3x 11x 23
987:3x 7x 47
799:17x 47
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 47 = 423
Therefore, the value for common factors is 423.
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 = 391456452618/(1x423)
LCM = 391456452618/423
LCM = 925428966
Thus, we can understand that the LCM of 654,759,987,799 is 925428966.
