Given numbers are 325,431,578,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 325,431,578,880 is 7124774800.
Find LCM of 325,431,578,880 with Prime Factorization
| 2 | 325, 431, 578, 880 |
| 5 | 325, 431, 289, 440 |
| 65, 431, 289, 88 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 65 x 431 x 289 x 88 = 7124774800
Therefore, the lowest common multiple of 325,431,578,880 is 7124774800.
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.
325 x 431 x 578 x 880 = 71247748000
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.
325 : 1, 5, 13, 25, 65, 325
431 : 1, 431
578 : 1, 2, 17, 34, 289, 578
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,431,578,880, is 1.
Now, the common factors can be found like this.
325:5x 5x 13
431:431
578:2x 17x 17
880:2x 2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 71247748000/(1x10)
LCM = 71247748000/10
LCM = 7124774800
Thus, we can understand that the LCM of 325,431,578,880 is 7124774800.
