Given numbers are 545,129,585,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,129,585,788 is 2160613260.
Find LCM of 545,129,585,788 with Prime Factorization
| 3 | 545, 129, 585, 788 |
| 5 | 545, 43, 195, 788 |
| 109, 43, 39, 788 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 109 x 43 x 39 x 788 = 2160613260
Therefore, the lowest common multiple of 545,129,585,788 is 2160613260.
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.
545 x 129 x 585 x 788 = 32409198900
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.
545 : 1, 5, 109, 545
129 : 1, 3, 43, 129
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,129,585,788, is 1.
Now, the common factors can be found like this.
545:5x 109
129:3x 43
585:3x 3x 5x 13
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 32409198900/(1x15)
LCM = 32409198900/15
LCM = 2160613260
Thus, we can understand that the LCM of 545,129,585,788 is 2160613260.
