Given numbers are 515,356,254,645,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,356,254,645,559 is 39047569860.
Find LCM of 515,356,254,645,559 with Prime Factorization
| 2 | 515, 356, 254, 645, 559 |
| 5 | 515, 178, 127, 645, 559 |
| 43 | 103, 178, 127, 129, 559 |
| 103, 178, 127, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 103 x 178 x 127 x 3 x 13 = 39047569860
Therefore, the lowest common multiple of 515,356,254,645,559 is 39047569860.
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 356 x 254 x 645 x 559 = 16790455039800
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
356 : 1, 2, 4, 89, 178, 356
254 : 1, 2, 127, 254
645 : 1, 3, 5, 15, 43, 129, 215, 645
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,356,254,645,559, is 1.
Now, the common factors can be found like this.
515:5x 103
356:2x 2x 89
254:2x 127
645:3x 5x 43
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 43 = 430
Therefore, the value for common factors is 430.
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 = 16790455039800/(1x430)
LCM = 16790455039800/430
LCM = 39047569860
Thus, we can understand that the LCM of 515,356,254,645,559 is 39047569860.
