Given numbers are 715,247,930,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,247,930,218 is 275422290.
Find LCM of 715,247,930,218 with Prime Factorization
| 2 | 715, 247, 930, 218 |
| 5 | 715, 247, 465, 109 |
| 13 | 143, 247, 93, 109 |
| 11, 19, 93, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 11 x 19 x 93 x 109 = 275422290
Therefore, the lowest common multiple of 715,247,930,218 is 275422290.
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.
715 x 247 x 930 x 218 = 35804897700
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
247 : 1, 13, 19, 247
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,247,930,218, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
247:13x 19
930:2x 3x 5x 31
218:2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 35804897700/(1x130)
LCM = 35804897700/130
LCM = 275422290
Thus, we can understand that the LCM of 715,247,930,218 is 275422290.
