Given numbers are 157,986,667,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,986,667,785 is 17802230.
Find LCM of 157,986,667,785 with Prime Factorization
| 29 | 157, 986, 667, 785 |
| 157 | 157, 34, 23, 785 |
| 1, 34, 23, 5 |
Multiply the prime numbers at the bottom and the left side.
29 x 157 x 1 x 34 x 23 x 5 = 17802230
Therefore, the lowest common multiple of 157,986,667,785 is 17802230.
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.
157 x 986 x 667 x 785 = 81053553190
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.
157 : 1, 157
986 : 1, 2, 17, 29, 34, 58, 493, 986
667 : 1, 23, 29, 667
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,986,667,785, is 1.
Now, the common factors can be found like this.
157:157
986:2x 17x 29
667:23x 29
785:5x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29x 157 = 4553
Therefore, the value for common factors is 4553.
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 = 81053553190/(1x4553)
LCM = 81053553190/4553
LCM = 17802230
Thus, we can understand that the LCM of 157,986,667,785 is 17802230.
