Given numbers are 578,680,361,384
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,680,361,384 is 200311680.
Find LCM of 578,680,361,384 with Prime Factorization
| 2 | 578, 680, 361, 384 |
| 2 | 289, 340, 361, 192 |
| 2 | 289, 170, 361, 96 |
| 17 | 289, 85, 361, 48 |
| 17, 5, 361, 48 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 17 x 5 x 361 x 48 = 200311680
Therefore, the lowest common multiple of 578,680,361,384 is 200311680.
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 680 x 361 x 384 = 54484776960
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
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
361 : 1, 19, 361
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,680,361,384, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
680:2x 2x 2x 5x 17
361:19x 19
384:2x 2x 2x 2x 2x 2x 2x 3
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 17 = 272
Therefore, the value for common factors is 272.
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 = 54484776960/(1x272)
LCM = 54484776960/272
LCM = 200311680
Thus, we can understand that the LCM of 578,680,361,384 is 200311680.
