Given numbers are 515,540,494,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,540,494,790 is 1085313060.
Find LCM of 515,540,494,790 with Prime Factorization
| 2 | 515, 540, 494, 790 |
| 5 | 515, 270, 247, 395 |
| 103, 54, 247, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 103 x 54 x 247 x 79 = 1085313060
Therefore, the lowest common multiple of 515,540,494,790 is 1085313060.
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.
515 x 540 x 494 x 790 = 108531306000
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.
515 : 1, 5, 103, 515
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
494 : 1, 2, 13, 19, 26, 38, 247, 494
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,540,494,790, is 1.
Now, the common factors can be found like this.
515:5x 103
540:2x 2x 3x 3x 3x 5
494:2x 13x 19
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 108531306000/(1x100)
LCM = 108531306000/100
LCM = 1085313060
Thus, we can understand that the LCM of 515,540,494,790 is 1085313060.
