Given numbers are 192,156,399,804,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 192,156,399,804,390 is 111209280.
Find LCM of 192,156,399,804,390 with Prime Factorization
| 2 | 192, 156, 399, 804, 390 |
| 2 | 96, 78, 399, 402, 195 |
| 3 | 48, 39, 399, 201, 195 |
| 13 | 16, 13, 133, 67, 65 |
| 16, 1, 133, 67, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 16 x 1 x 133 x 67 x 5 = 111209280
Therefore, the lowest common multiple of 192,156,399,804,390 is 111209280.
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.
192 x 156 x 399 x 804 x 390 = 3747307898880
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
399 : 1, 3, 7, 19, 21, 57, 133, 399
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,156,399,804,390, is 3.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
156:2x 2x 3x 13
399:3x 7x 19
804:2x 2x 3x 67
390:2x 3x 5x 13
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 3x 3x 3x 13 = 11232
Therefore, the value for common factors is 11232.
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 = 3747307898880/(3x11232)
LCM = 3747307898880/33696
LCM = 111209280
Thus, we can understand that the LCM of 192,156,399,804,390 is 111209280.
