Given numbers are 157,819,314,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,819,314,531 is 15172794.
Find LCM of 157,819,314,531 with Prime Factorization
| 3 | 157, 819, 314, 531 |
| 3 | 157, 273, 314, 177 |
| 157 | 157, 91, 314, 59 |
| 1, 91, 2, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 157 x 1 x 91 x 2 x 59 = 15172794
Therefore, the lowest common multiple of 157,819,314,531 is 15172794.
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 819 x 314 x 531 = 21439157922
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
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
314 : 1, 2, 157, 314
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,819,314,531, is 1.
Now, the common factors can be found like this.
157:157
819:3x 3x 7x 13
314:2x 157
531:3x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 157 = 1413
Therefore, the value for common factors is 1413.
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 = 21439157922/(1x1413)
LCM = 21439157922/1413
LCM = 15172794
Thus, we can understand that the LCM of 157,819,314,531 is 15172794.
