Given numbers are 251,754,905,954,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,754,905,954,170 is 1388867920830.
Find LCM of 251,754,905,954,170 with Prime Factorization
| 2 | 251, 754, 905, 954, 170 |
| 5 | 251, 377, 905, 477, 85 |
| 251, 377, 181, 477, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 251 x 377 x 181 x 477 x 17 = 1388867920830
Therefore, the lowest common multiple of 251,754,905,954,170 is 1388867920830.
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.
251 x 754 x 905 x 954 x 170 = 27777358416600
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.
251 : 1, 251
754 : 1, 2, 13, 26, 29, 58, 377, 754
905 : 1, 5, 181, 905
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,754,905,954,170, is 1.
Now, the common factors can be found like this.
251:251
754:2x 13x 29
905:5x 181
954:2x 3x 3x 53
170:2x 5x 17
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 5 = 20
Therefore, the value for common factors is 20.
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 = 27777358416600/(1x20)
LCM = 27777358416600/20
LCM = 1388867920830
Thus, we can understand that the LCM of 251,754,905,954,170 is 1388867920830.
