Given numbers are 427,442,932,390,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,442,932,390,656 is 216357108240.
Find LCM of 427,442,932,390,656 with Prime Factorization
| 2 | 427, 442, 932, 390, 656 |
| 2 | 427, 221, 466, 195, 328 |
| 13 | 427, 221, 233, 195, 164 |
| 427, 17, 233, 15, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 427 x 17 x 233 x 15 x 164 = 216357108240
Therefore, the lowest common multiple of 427,442,932,390,656 is 216357108240.
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.
427 x 442 x 932 x 390 x 656 = 45002278513920
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.
427 : 1, 7, 61, 427
442 : 1, 2, 13, 17, 26, 34, 221, 442
932 : 1, 2, 4, 233, 466, 932
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,442,932,390,656, is 1.
Now, the common factors can be found like this.
427:7x 61
442:2x 13x 17
932:2x 2x 233
390:2x 3x 5x 13
656:2x 2x 2x 2x 41
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 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 45002278513920/(1x208)
LCM = 45002278513920/208
LCM = 216357108240
Thus, we can understand that the LCM of 427,442,932,390,656 is 216357108240.
