Given numbers are 718,544,245,782,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,544,245,782,686 is 7703450720.
Find LCM of 718,544,245,782,686 with Prime Factorization
| 2 | 718, 544, 245, 782, 686 |
| 7 | 359, 272, 245, 391, 343 |
| 7 | 359, 272, 35, 391, 49 |
| 17 | 359, 272, 5, 391, 7 |
| 359, 16, 5, 23, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 17 x 359 x 16 x 5 x 23 x 7 = 7703450720
Therefore, the lowest common multiple of 718,544,245,782,686 is 7703450720.
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.
718 x 544 x 245 x 782 x 686 = 51335795598080
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.
718 : 1, 2, 359, 718
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
245 : 1, 5, 7, 35, 49, 245
782 : 1, 2, 17, 23, 34, 46, 391, 782
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,544,245,782,686, is 1.
Now, the common factors can be found like this.
718:2x 359
544:2x 2x 2x 2x 2x 17
245:5x 7x 7
782:2x 17x 23
686:2x 7x 7x 7
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 7x 7x 17 = 6664
Therefore, the value for common factors is 6664.
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 = 51335795598080/(1x6664)
LCM = 51335795598080/6664
LCM = 7703450720
Thus, we can understand that the LCM of 718,544,245,782,686 is 7703450720.
