Given numbers are 515,635,309,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,635,309,688 is 134995920.
Find LCM of 515,635,309,688 with Prime Factorization
| 5 | 515, 635, 309, 688 |
| 103 | 103, 127, 309, 688 |
| 1, 127, 3, 688 |
Multiply the prime numbers at the bottom and the left side.
5 x 103 x 1 x 127 x 3 x 688 = 134995920
Therefore, the lowest common multiple of 515,635,309,688 is 134995920.
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 635 x 309 x 688 = 69522898800
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
635 : 1, 5, 127, 635
309 : 1, 3, 103, 309
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,635,309,688, is 1.
Now, the common factors can be found like this.
515:5x 103
635:5x 127
309:3x 103
688:2x 2x 2x 2x 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 103 = 515
Therefore, the value for common factors is 515.
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 = 69522898800/(1x515)
LCM = 69522898800/515
LCM = 134995920
Thus, we can understand that the LCM of 515,635,309,688 is 134995920.
