Given numbers are 770,703,950,656,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,703,950,656,457 is 405701018800.
Find LCM of 770,703,950,656,457 with Prime Factorization
| 2 | 770, 703, 950, 656, 457 |
| 5 | 385, 703, 475, 328, 457 |
| 19 | 77, 703, 95, 328, 457 |
| 77, 37, 5, 328, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 77 x 37 x 5 x 328 x 457 = 405701018800
Therefore, the lowest common multiple of 770,703,950,656,457 is 405701018800.
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.
770 x 703 x 950 x 656 x 457 = 154166387144000
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
703 : 1, 19, 37, 703
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,703,950,656,457, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
703:19x 37
950:2x 5x 5x 19
656:2x 2x 2x 2x 41
457:457
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 154166387144000/(1x380)
LCM = 154166387144000/380
LCM = 405701018800
Thus, we can understand that the LCM of 770,703,950,656,457 is 405701018800.
