Given numbers are 904,418,489,570
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,418,489,570 is 461948520.
Find LCM of 904,418,489,570 with Prime Factorization
| 2 | 904, 418, 489, 570 |
| 3 | 452, 209, 489, 285 |
| 19 | 452, 209, 163, 95 |
| 452, 11, 163, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 452 x 11 x 163 x 5 = 461948520
Therefore, the lowest common multiple of 904,418,489,570 is 461948520.
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.
904 x 418 x 489 x 570 = 105324262560
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
418 : 1, 2, 11, 19, 22, 38, 209, 418
489 : 1, 3, 163, 489
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,418,489,570, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
418:2x 11x 19
489:3x 163
570:2x 3x 5x 19
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 19 = 228
Therefore, the value for common factors is 228.
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 = 105324262560/(1x228)
LCM = 105324262560/228
LCM = 461948520
Thus, we can understand that the LCM of 904,418,489,570 is 461948520.
