Given numbers are 703,855,642,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 703,855,642,121 is 819156690.
Find LCM of 703,855,642,121 with Prime Factorization
| 3 | 703, 855, 642, 121 |
| 19 | 703, 285, 214, 121 |
| 37, 15, 214, 121 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 37 x 15 x 214 x 121 = 819156690
Therefore, the lowest common multiple of 703,855,642,121 is 819156690.
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 855 x 642 x 121 = 46691931330
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
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
642 : 1, 2, 3, 6, 107, 214, 321, 642
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 703,855,642,121, is 1.
Now, the common factors can be found like this.
703:19x 37
855:3x 3x 5x 19
642:2x 3x 107
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 46691931330/(1x57)
LCM = 46691931330/57
LCM = 819156690
Thus, we can understand that the LCM of 703,855,642,121 is 819156690.
