Given numbers are 578,755,425,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,755,425,387 is 844414650.
Find LCM of 578,755,425,387 with Prime Factorization
| 5 | 578, 755, 425, 387 |
| 17 | 578, 151, 85, 387 |
| 34, 151, 5, 387 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 34 x 151 x 5 x 387 = 844414650
Therefore, the lowest common multiple of 578,755,425,387 is 844414650.
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.
578 x 755 x 425 x 387 = 71775245250
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.
578 : 1, 2, 17, 34, 289, 578
755 : 1, 5, 151, 755
425 : 1, 5, 17, 25, 85, 425
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,755,425,387, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
755:5x 151
425:5x 5x 17
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 17 = 85
Therefore, the value for common factors is 85.
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 = 71775245250/(1x85)
LCM = 71775245250/85
LCM = 844414650
Thus, we can understand that the LCM of 578,755,425,387 is 844414650.
