Given numbers are 298,402,902,381,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,402,902,381,561 is 58323221682.
Find LCM of 298,402,902,381,561 with Prime Factorization
| 2 | 298, 402, 902, 381, 561 |
| 3 | 149, 201, 451, 381, 561 |
| 11 | 149, 67, 451, 127, 187 |
| 149, 67, 41, 127, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 149 x 67 x 41 x 127 x 17 = 58323221682
Therefore, the lowest common multiple of 298,402,902,381,561 is 58323221682.
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.
298 x 402 x 902 x 381 x 561 = 23095995786072
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.
298 : 1, 2, 149, 298
402 : 1, 2, 3, 6, 67, 134, 201, 402
902 : 1, 2, 11, 22, 41, 82, 451, 902
381 : 1, 3, 127, 381
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,402,902,381,561, is 1.
Now, the common factors can be found like this.
298:2x 149
402:2x 3x 67
902:2x 11x 41
381:3x 127
561:3x 11x 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 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 23095995786072/(1x396)
LCM = 23095995786072/396
LCM = 58323221682
Thus, we can understand that the LCM of 298,402,902,381,561 is 58323221682.
