Given numbers are 614,420,740,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 614,420,740,406 is 138352620.
Find LCM of 614,420,740,406 with Prime Factorization
| 2 | 614, 420, 740, 406 |
| 2 | 307, 210, 370, 203 |
| 5 | 307, 105, 185, 203 |
| 7 | 307, 21, 37, 203 |
| 307, 3, 37, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 307 x 3 x 37 x 29 = 138352620
Therefore, the lowest common multiple of 614,420,740,406 is 138352620.
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.
614 x 420 x 740 x 406 = 77477467200
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.
614 : 1, 2, 307, 614
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
406 : 1, 2, 7, 14, 29, 58, 203, 406
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 614,420,740,406, is 2.
Now, the common factors can be found like this.
614:2x 307
420:2x 2x 3x 5x 7
740:2x 2x 5x 37
406:2x 7x 29
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 77477467200/(2x280)
LCM = 77477467200/560
LCM = 138352620
Thus, we can understand that the LCM of 614,420,740,406 is 138352620.
