Given numbers are 667,313,272,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,313,272,644 is 397499984.
Find LCM of 667,313,272,644 with Prime Factorization
| 2 | 667, 313, 272, 644 |
| 2 | 667, 313, 136, 322 |
| 23 | 667, 313, 68, 161 |
| 29, 313, 68, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 29 x 313 x 68 x 7 = 397499984
Therefore, the lowest common multiple of 667,313,272,644 is 397499984.
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.
667 x 313 x 272 x 644 = 36569998528
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.
667 : 1, 23, 29, 667
313 : 1, 313
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,313,272,644, is 1.
Now, the common factors can be found like this.
667:23x 29
313:313
272:2x 2x 2x 2x 17
644:2x 2x 7x 23
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 23 = 92
Therefore, the value for common factors is 92.
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 = 36569998528/(1x92)
LCM = 36569998528/92
LCM = 397499984
Thus, we can understand that the LCM of 667,313,272,644 is 397499984.
