Given numbers are 415,870,381,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 415,870,381,188 is 862042980.
Find LCM of 415,870,381,188 with Prime Factorization
| 2 | 415, 870, 381, 188 |
| 3 | 415, 435, 381, 94 |
| 5 | 415, 145, 127, 94 |
| 83, 29, 127, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 83 x 29 x 127 x 94 = 862042980
Therefore, the lowest common multiple of 415,870,381,188 is 862042980.
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.
415 x 870 x 381 x 188 = 25861289400
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.
415 : 1, 5, 83, 415
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
381 : 1, 3, 127, 381
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,870,381,188, is 1.
Now, the common factors can be found like this.
415:5x 83
870:2x 3x 5x 29
381:3x 127
188:2x 2x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 25861289400/(1x30)
LCM = 25861289400/30
LCM = 862042980
Thus, we can understand that the LCM of 415,870,381,188 is 862042980.
