Given numbers are 254,754,638,359
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,754,638,359 is 378148342.
Find LCM of 254,754,638,359 with Prime Factorization
| 2 | 254, 754, 638, 359 |
| 29 | 127, 377, 319, 359 |
| 127, 13, 11, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 127 x 13 x 11 x 359 = 378148342
Therefore, the lowest common multiple of 254,754,638,359 is 378148342.
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.
254 x 754 x 638 x 359 = 43865207672
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.
254 : 1, 2, 127, 254
754 : 1, 2, 13, 26, 29, 58, 377, 754
638 : 1, 2, 11, 22, 29, 58, 319, 638
359 : 1, 359
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,754,638,359, is 1.
Now, the common factors can be found like this.
254:2x 127
754:2x 13x 29
638:2x 11x 29
359:359
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 29 = 116
Therefore, the value for common factors is 116.
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 = 43865207672/(1x116)
LCM = 43865207672/116
LCM = 378148342
Thus, we can understand that the LCM of 254,754,638,359 is 378148342.
