Given numbers are 387,266,736,671,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,266,736,671,981 is 2770699577184.
Find LCM of 387,266,736,671,981 with Prime Factorization
| 2 | 387, 266, 736, 671, 981 |
| 3 | 387, 133, 368, 671, 981 |
| 3 | 129, 133, 368, 671, 327 |
| 43, 133, 368, 671, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 43 x 133 x 368 x 671 x 109 = 2770699577184
Therefore, the lowest common multiple of 387,266,736,671,981 is 2770699577184.
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.
387 x 266 x 736 x 671 x 981 = 49872592389312
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.
387 : 1, 3, 9, 43, 129, 387
266 : 1, 2, 7, 14, 19, 38, 133, 266
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
671 : 1, 11, 61, 671
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,266,736,671,981, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
266:2x 7x 19
736:2x 2x 2x 2x 2x 23
671:11x 61
981:3x 3x 109
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 3 = 18
Therefore, the value for common factors is 18.
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 = 49872592389312/(1x18)
LCM = 49872592389312/18
LCM = 2770699577184
Thus, we can understand that the LCM of 387,266,736,671,981 is 2770699577184.
