The LCM of 291,682,785,638,776 is 18071949720.
Find LCM of 291,682,785,638,776 with Prime Factorization
| 2 | 291, 682, 785, 638, 776 |
| 11 | 291, 341, 785, 319, 388 |
| 97 | 291, 31, 785, 29, 388 |
| 3, 31, 785, 29, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 97 x 3 x 31 x 785 x 29 x 4 = 18071949720
Therefore, the lowest common multiple of 291,682,785,638,776 is 18071949720.
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.
291 x 682 x 785 x 638 x 776 = 77131081404960
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.
291 : 1, 3, 97, 291
682 : 1, 2, 11, 22, 31, 62, 341, 682
785 : 1, 5, 157, 785
638 : 1, 2, 11, 22, 29, 58, 319, 638
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,682,785,638,776, is 1.
Now, the common factors can be found like this.
291:3x 97
682:2x 11x 31
785:5x 157
638:2x 11x 29
776:2x 2x 2x 97
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 11x 97 = 4268
Therefore, the value for common factors is 4268.
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 = 77131081404960/(1x4268)
LCM = 77131081404960/4268
LCM = 18071949720
Thus, we can understand that the LCM of 291,682,785,638,776 is 18071949720.
