Given numbers are 378,815,518,902,962
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,815,518,902,962 is 66829933170.
Find LCM of 378,815,518,902,962 with Prime Factorization
| 2 | 378, 815, 518, 902, 962 |
| 7 | 189, 815, 259, 451, 481 |
| 37 | 27, 815, 37, 451, 481 |
| 27, 815, 1, 451, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 37 x 27 x 815 x 1 x 451 x 13 = 66829933170
Therefore, the lowest common multiple of 378,815,518,902,962 is 66829933170.
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 815 x 518 x 902 x 962 = 138471621528240
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
815 : 1, 5, 163, 815
518 : 1, 2, 7, 14, 37, 74, 259, 518
902 : 1, 2, 11, 22, 41, 82, 451, 902
962 : 1, 2, 13, 26, 37, 74, 481, 962
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,815,518,902,962, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
815:5x 163
518:2x 7x 37
902:2x 11x 41
962:2x 13x 37
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 2x 7x 37 = 2072
Therefore, the value for common factors is 2072.
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 = 138471621528240/(1x2072)
LCM = 138471621528240/2072
LCM = 66829933170
Thus, we can understand that the LCM of 378,815,518,902,962 is 66829933170.
