Given numbers are 670,380,747,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,380,747,540 is 57055860.
Find LCM of 670,380,747,540 with Prime Factorization
| 2 | 670, 380, 747, 540 |
| 2 | 335, 190, 747, 270 |
| 3 | 335, 95, 747, 135 |
| 3 | 335, 95, 249, 45 |
| 5 | 335, 95, 83, 15 |
| 67, 19, 83, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 67 x 19 x 83 x 3 = 57055860
Therefore, the lowest common multiple of 670,380,747,540 is 57055860.
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.
670 x 380 x 747 x 540 = 102700548000
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
747 : 1, 3, 9, 83, 249, 747
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,380,747,540, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
380:2x 2x 5x 19
747:3x 3x 83
540:2x 2x 3x 3x 3x 5
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 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 102700548000/(1x1800)
LCM = 102700548000/1800
LCM = 57055860
Thus, we can understand that the LCM of 670,380,747,540 is 57055860.
