Given numbers are 604,392,840,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 604,392,840,868 is 27524280.
Find LCM of 604,392,840,868 with Prime Factorization
| 2 | 604, 392, 840, 868 |
| 2 | 302, 196, 420, 434 |
| 2 | 151, 98, 210, 217 |
| 7 | 151, 49, 105, 217 |
| 151, 7, 15, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 151 x 7 x 15 x 31 = 27524280
Therefore, the lowest common multiple of 604,392,840,868 is 27524280.
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.
604 x 392 x 840 x 868 = 172632284160
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.
604 : 1, 2, 4, 151, 302, 604
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 604,392,840,868, is 4.
Now, the common factors can be found like this.
604:2x 2x 151
392:2x 2x 2x 7x 7
840:2x 2x 2x 3x 5x 7
868:2x 2x 7x 31
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 2x 7x 7 = 1568
Therefore, the value for common factors is 1568.
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 = 172632284160/(4x1568)
LCM = 172632284160/6272
LCM = 27524280
Thus, we can understand that the LCM of 604,392,840,868 is 27524280.
