Given numbers are 785,390,914,457,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,390,914,457,288 is 1343141280.
Find LCM of 785,390,914,457,288 with Prime Factorization
| 2 | 785, 390, 914, 457, 288 |
| 3 | 785, 195, 457, 457, 144 |
| 5 | 785, 65, 457, 457, 48 |
| 457 | 157, 13, 457, 457, 48 |
| 157, 13, 1, 1, 48 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 457 x 157 x 13 x 1 x 1 x 48 = 1343141280
Therefore, the lowest common multiple of 785,390,914,457,288 is 1343141280.
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.
785 x 390 x 914 x 457 x 288 = 36828933897600
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.
785 : 1, 5, 157, 785
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
914 : 1, 2, 457, 914
457 : 1, 457
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,390,914,457,288, is 1.
Now, the common factors can be found like this.
785:5x 157
390:2x 3x 5x 13
914:2x 457
457:457
288:2x 2x 2x 2x 2x 3x 3
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 3x 5x 457 = 27420
Therefore, the value for common factors is 27420.
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 = 36828933897600/(1x27420)
LCM = 36828933897600/27420
LCM = 1343141280
Thus, we can understand that the LCM of 785,390,914,457,288 is 1343141280.
