Given numbers are 715,701,388,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,701,388,315 is 12251699460.
Find LCM of 715,701,388,315 with Prime Factorization
| 5 | 715, 701, 388, 315 |
| 143, 701, 388, 63 |
Multiply the prime numbers at the bottom and the left side.
5 x 143 x 701 x 388 x 63 = 12251699460
Therefore, the lowest common multiple of 715,701,388,315 is 12251699460.
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 701 x 388 x 315 = 61258497300
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
701 : 1, 701
388 : 1, 2, 4, 97, 194, 388
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,701,388,315, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
701:701
388:2x 2x 97
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 61258497300/(1x5)
LCM = 61258497300/5
LCM = 12251699460
Thus, we can understand that the LCM of 715,701,388,315 is 12251699460.
