Given numbers are 124,357,208,787,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 124,357,208,787,870 is 262685426640.
Find LCM of 124,357,208,787,870 with Prime Factorization
| 2 | 124, 357, 208, 787, 870 |
| 2 | 62, 357, 104, 787, 435 |
| 3 | 31, 357, 52, 787, 435 |
| 31, 119, 52, 787, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 119 x 52 x 787 x 145 = 262685426640
Therefore, the lowest common multiple of 124,357,208,787,870 is 262685426640.
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.
124 x 357 x 208 x 787 x 870 = 6304450239360
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.
124 : 1, 2, 4, 31, 62, 124
357 : 1, 3, 7, 17, 21, 51, 119, 357
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
787 : 1, 787
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 124,357,208,787,870, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
357:3x 7x 17
208:2x 2x 2x 2x 13
787:787
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 3 = 24
Therefore, the value for common factors is 24.
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 = 6304450239360/(1x24)
LCM = 6304450239360/24
LCM = 262685426640
Thus, we can understand that the LCM of 124,357,208,787,870 is 262685426640.
