Given numbers are 500,700,394,285,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 500,700,394,285,974 is 19139830500.
Find LCM of 500,700,394,285,974 with Prime Factorization
| 2 | 500, 700, 394, 285, 974 |
| 2 | 250, 350, 197, 285, 487 |
| 5 | 125, 175, 197, 285, 487 |
| 5 | 25, 35, 197, 57, 487 |
| 5, 7, 197, 57, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 5 x 7 x 197 x 57 x 487 = 19139830500
Therefore, the lowest common multiple of 500,700,394,285,974 is 19139830500.
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.
500 x 700 x 394 x 285 x 974 = 38279661000000
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.
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
394 : 1, 2, 197, 394
285 : 1, 3, 5, 15, 19, 57, 95, 285
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 500,700,394,285,974, is 1.
Now, the common factors can be found like this.
500:2x 2x 5x 5x 5
700:2x 2x 5x 5x 7
394:2x 197
285:3x 5x 19
974:2x 487
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 5x 5x 5 = 2000
Therefore, the value for common factors is 2000.
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 = 38279661000000/(1x2000)
LCM = 38279661000000/2000
LCM = 19139830500
Thus, we can understand that the LCM of 500,700,394,285,974 is 19139830500.
