Given numbers are 723,442,393,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,442,393,578 is 711673482.
Find LCM of 723,442,393,578 with Prime Factorization
2 | 723, 442, 393, 578 |
3 | 723, 221, 393, 289 |
17 | 241, 221, 131, 289 |
241, 13, 131, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 241 x 13 x 131 x 17 = 711673482
Therefore, the lowest common multiple of 723,442,393,578 is 711673482.
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.
723 x 442 x 393 x 578 = 72590695164
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.
723 : 1, 3, 241, 723
442 : 1, 2, 13, 17, 26, 34, 221, 442
393 : 1, 3, 131, 393
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,442,393,578, is 1.
Now, the common factors can be found like this.
723:3x 241
442:2x 13x 17
393:3x 131
578:2x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 72590695164/(1x102)
LCM = 72590695164/102
LCM = 711673482
Thus, we can understand that the LCM of 723,442,393,578 is 711673482.
