Given numbers are 838,378,981,653
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,378,981,653 is 11273155614.
Find LCM of 838,378,981,653 with Prime Factorization
| 2 | 838, 378, 981, 653 |
| 3 | 419, 189, 981, 653 |
| 3 | 419, 63, 327, 653 |
| 419, 21, 109, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 419 x 21 x 109 x 653 = 11273155614
Therefore, the lowest common multiple of 838,378,981,653 is 11273155614.
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.
838 x 378 x 981 x 653 = 202916801052
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.
838 : 1, 2, 419, 838
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
981 : 1, 3, 9, 109, 327, 981
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,378,981,653, is 1.
Now, the common factors can be found like this.
838:2x 419
378:2x 3x 3x 3x 7
981:3x 3x 109
653:653
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 202916801052/(1x18)
LCM = 202916801052/18
LCM = 11273155614
Thus, we can understand that the LCM of 838,378,981,653 is 11273155614.
