Given numbers are 515,763,145,628,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,763,145,628,261 is 64406829060.
Find LCM of 515,763,145,628,261 with Prime Factorization
| 5 | 515, 763, 145, 628, 261 |
| 29 | 103, 763, 29, 628, 261 |
| 103, 763, 1, 628, 9 |
Multiply the prime numbers at the bottom and the left side.
5 x 29 x 103 x 763 x 1 x 628 x 9 = 64406829060
Therefore, the lowest common multiple of 515,763,145,628,261 is 64406829060.
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 763 x 145 x 628 x 261 = 9338990213700
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
763 : 1, 7, 109, 763
145 : 1, 5, 29, 145
628 : 1, 2, 4, 157, 314, 628
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,763,145,628,261, is 1.
Now, the common factors can be found like this.
515:5x 103
763:7x 109
145:5x 29
628:2x 2x 157
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 29 = 145
Therefore, the value for common factors is 145.
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 = 9338990213700/(1x145)
LCM = 9338990213700/145
LCM = 64406829060
Thus, we can understand that the LCM of 515,763,145,628,261 is 64406829060.
