Given numbers are 157,400,788,754,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,400,788,754,986 is 79289584400.
Find LCM of 157,400,788,754,986 with Prime Factorization
| 2 | 157, 400, 788, 754, 986 |
| 2 | 157, 200, 394, 377, 493 |
| 29 | 157, 100, 197, 377, 493 |
| 157, 100, 197, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 157 x 100 x 197 x 13 x 17 = 79289584400
Therefore, the lowest common multiple of 157,400,788,754,986 is 79289584400.
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 400 x 788 x 754 x 986 = 36790367161600
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
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
788 : 1, 2, 4, 197, 394, 788
754 : 1, 2, 13, 26, 29, 58, 377, 754
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,400,788,754,986, is 1.
Now, the common factors can be found like this.
157:157
400:2x 2x 2x 2x 5x 5
788:2x 2x 197
754:2x 13x 29
986:2x 17x 29
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 2x 2x 29 = 464
Therefore, the value for common factors is 464.
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 = 36790367161600/(1x464)
LCM = 36790367161600/464
LCM = 79289584400
Thus, we can understand that the LCM of 157,400,788,754,986 is 79289584400.
