Given numbers are 524,705,396,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 524,705,396,870 is 353534940.
Find LCM of 524,705,396,870 with Prime Factorization
| 2 | 524, 705, 396, 870 |
| 2 | 262, 705, 198, 435 |
| 3 | 131, 705, 99, 435 |
| 5 | 131, 235, 33, 145 |
| 131, 47, 33, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 131 x 47 x 33 x 29 = 353534940
Therefore, the lowest common multiple of 524,705,396,870 is 353534940.
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.
524 x 705 x 396 x 870 = 127272578400
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.
524 : 1, 2, 4, 131, 262, 524
705 : 1, 3, 5, 15, 47, 141, 235, 705
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,705,396,870, is 1.
Now, the common factors can be found like this.
524:2x 2x 131
705:3x 5x 47
396:2x 2x 3x 3x 11
870:2x 3x 5x 29
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 127272578400/(1x360)
LCM = 127272578400/360
LCM = 353534940
Thus, we can understand that the LCM of 524,705,396,870 is 353534940.
