Given numbers are 468,390,628,349
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,390,628,349 is 128215620.
Find LCM of 468,390,628,349 with Prime Factorization
2 | 468, 390, 628, 349 |
2 | 234, 195, 314, 349 |
3 | 117, 195, 157, 349 |
13 | 39, 65, 157, 349 |
3, 5, 157, 349 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 3 x 5 x 157 x 349 = 128215620
Therefore, the lowest common multiple of 468,390,628,349 is 128215620.
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.
468 x 390 x 628 x 349 = 40003273440
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
628 : 1, 2, 4, 157, 314, 628
349 : 1, 349
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,390,628,349, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
390:2x 3x 5x 13
628:2x 2x 157
349:349
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 2x 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 40003273440/(1x312)
LCM = 40003273440/312
LCM = 128215620
Thus, we can understand that the LCM of 468,390,628,349 is 128215620.
