Given numbers are 378,440,131,671,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,440,131,671,474 is 52497993240.
Find LCM of 378,440,131,671,474 with Prime Factorization
| 2 | 378, 440, 131, 671, 474 |
| 3 | 189, 220, 131, 671, 237 |
| 11 | 63, 220, 131, 671, 79 |
| 63, 20, 131, 61, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 63 x 20 x 131 x 61 x 79 = 52497993240
Therefore, the lowest common multiple of 378,440,131,671,474 is 52497993240.
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.
378 x 440 x 131 x 671 x 474 = 6929735107680
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
131 : 1, 131
671 : 1, 11, 61, 671
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,440,131,671,474, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
440:2x 2x 2x 5x 11
131:131
671:11x 61
474:2x 3x 79
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 11 = 132
Therefore, the value for common factors is 132.
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 = 6929735107680/(1x132)
LCM = 6929735107680/132
LCM = 52497993240
Thus, we can understand that the LCM of 378,440,131,671,474 is 52497993240.
