Given numbers are 578,306,265,621,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,306,265,621,454 is 21591915390.
Find LCM of 578,306,265,621,454 with Prime Factorization
| 2 | 578, 306, 265, 621, 454 |
| 3 | 289, 153, 265, 621, 227 |
| 3 | 289, 51, 265, 207, 227 |
| 17 | 289, 17, 265, 69, 227 |
| 1, 17, 265, 69, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 1 x 17 x 265 x 69 x 227 = 21591915390
Therefore, the lowest common multiple of 578,306,265,621,454 is 21591915390.
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 306 x 265 x 621 x 454 = 13214252218680
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
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
265 : 1, 5, 53, 265
621 : 1, 3, 9, 23, 27, 69, 207, 621
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,306,265,621,454, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
306:2x 3x 3x 17
265:5x 53
621:3x 3x 3x 23
454:2x 227
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 13214252218680/(1x612)
LCM = 13214252218680/612
LCM = 21591915390
Thus, we can understand that the LCM of 578,306,265,621,454 is 21591915390.
