Given numbers are 392,684,300,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,684,300,804 is 112278600.
Find LCM of 392,684,300,804 with Prime Factorization
| 2 | 392, 684, 300, 804 |
| 2 | 196, 342, 150, 402 |
| 3 | 98, 171, 75, 201 |
| 98, 57, 25, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 98 x 57 x 25 x 67 = 112278600
Therefore, the lowest common multiple of 392,684,300,804 is 112278600.
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.
392 x 684 x 300 x 804 = 64672473600
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,684,300,804, is 4.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
684:2x 2x 3x 3x 19
300:2x 2x 3x 5x 5
804:2x 2x 3x 67
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 64672473600/(4x144)
LCM = 64672473600/576
LCM = 112278600
Thus, we can understand that the LCM of 392,684,300,804 is 112278600.
