Given numbers are 615,379,760,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,379,760,429 is 5066335560.
Find LCM of 615,379,760,429 with Prime Factorization
| 3 | 615, 379, 760, 429 |
| 5 | 205, 379, 760, 143 |
| 41, 379, 152, 143 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 41 x 379 x 152 x 143 = 5066335560
Therefore, the lowest common multiple of 615,379,760,429 is 5066335560.
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.
615 x 379 x 760 x 429 = 75995033400
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
379 : 1, 379
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,379,760,429, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
379:379
760:2x 2x 2x 5x 19
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 75995033400/(1x15)
LCM = 75995033400/15
LCM = 5066335560
Thus, we can understand that the LCM of 615,379,760,429 is 5066335560.
