Given numbers are 703,718,760,407,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 703,718,760,407,686 is 38088736840.
Find LCM of 703,718,760,407,686 with Prime Factorization
| 2 | 703, 718, 760, 407, 686 |
| 19 | 703, 359, 380, 407, 343 |
| 37 | 37, 359, 20, 407, 343 |
| 1, 359, 20, 11, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 37 x 1 x 359 x 20 x 11 x 343 = 38088736840
Therefore, the lowest common multiple of 703,718,760,407,686 is 38088736840.
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.
703 x 718 x 760 x 407 x 686 = 107105527994080
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.
703 : 1, 19, 37, 703
718 : 1, 2, 359, 718
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
407 : 1, 11, 37, 407
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 703,718,760,407,686, is 1.
Now, the common factors can be found like this.
703:19x 37
718:2x 359
760:2x 2x 2x 5x 19
407:11x 37
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 19x 37 = 2812
Therefore, the value for common factors is 2812.
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 = 107105527994080/(1x2812)
LCM = 107105527994080/2812
LCM = 38088736840
Thus, we can understand that the LCM of 703,718,760,407,686 is 38088736840.
