Given numbers are 578,437,969,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,437,969,842 is 319016118.
Find LCM of 578,437,969,842 with Prime Factorization
| 2 | 578, 437, 969, 842 |
| 17 | 289, 437, 969, 421 |
| 19 | 17, 437, 57, 421 |
| 17, 23, 3, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 17 x 23 x 3 x 421 = 319016118
Therefore, the lowest common multiple of 578,437,969,842 is 319016118.
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.
578 x 437 x 969 x 842 = 206084412228
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.
578 : 1, 2, 17, 34, 289, 578
437 : 1, 19, 23, 437
969 : 1, 3, 17, 19, 51, 57, 323, 969
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,437,969,842, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
437:19x 23
969:3x 17x 19
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 19 = 646
Therefore, the value for common factors is 646.
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 = 206084412228/(1x646)
LCM = 206084412228/646
LCM = 319016118
Thus, we can understand that the LCM of 578,437,969,842 is 319016118.
