Given numbers are 781,482,754,605,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,482,754,605,961 is 7501109400070.
Find LCM of 781,482,754,605,961 with Prime Factorization
| 2 | 781, 482, 754, 605, 961 |
| 11 | 781, 241, 377, 605, 961 |
| 71, 241, 377, 55, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 241 x 377 x 55 x 961 = 7501109400070
Therefore, the lowest common multiple of 781,482,754,605,961 is 7501109400070.
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.
781 x 482 x 754 x 605 x 961 = 165024406801540
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.
781 : 1, 11, 71, 781
482 : 1, 2, 241, 482
754 : 1, 2, 13, 26, 29, 58, 377, 754
605 : 1, 5, 11, 55, 121, 605
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,482,754,605,961, is 1.
Now, the common factors can be found like this.
781:11x 71
482:2x 241
754:2x 13x 29
605:5x 11x 11
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 165024406801540/(1x22)
LCM = 165024406801540/22
LCM = 7501109400070
Thus, we can understand that the LCM of 781,482,754,605,961 is 7501109400070.
