Given numbers are 157,991,428,852,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,991,428,852,401 is 5687757240468.
Find LCM of 157,991,428,852,401 with Prime Factorization
| 2 | 157, 991, 428, 852, 401 |
| 2 | 157, 991, 214, 426, 401 |
| 157, 991, 107, 213, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 157 x 991 x 107 x 213 x 401 = 5687757240468
Therefore, the lowest common multiple of 157,991,428,852,401 is 5687757240468.
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 991 x 428 x 852 x 401 = 22751028961872
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
991 : 1, 991
428 : 1, 2, 4, 107, 214, 428
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,991,428,852,401, is 1.
Now, the common factors can be found like this.
157:157
991:991
428:2x 2x 107
852:2x 2x 3x 71
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 22751028961872/(1x4)
LCM = 22751028961872/4
LCM = 5687757240468
Thus, we can understand that the LCM of 157,991,428,852,401 is 5687757240468.
