Given numbers are 420,364,629,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,364,629,609 is 99595860.
Find LCM of 420,364,629,609 with Prime Factorization
| 2 | 420, 364, 629, 609 |
| 2 | 210, 182, 629, 609 |
| 3 | 105, 91, 629, 609 |
| 7 | 35, 91, 629, 203 |
| 5, 13, 629, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 13 x 629 x 29 = 99595860
Therefore, the lowest common multiple of 420,364,629,609 is 99595860.
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.
420 x 364 x 629 x 609 = 58562365680
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.
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
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
629 : 1, 17, 37, 629
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,364,629,609, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
364:2x 2x 7x 13
629:17x 37
609:3x 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 3x 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 58562365680/(1x588)
LCM = 58562365680/588
LCM = 99595860
Thus, we can understand that the LCM of 420,364,629,609 is 99595860.
