Given numbers are 818,715,640,847,477
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,715,640,847,477 is 1374828174720.
Find LCM of 818,715,640,847,477 with Prime Factorization
| 2 | 818, 715, 640, 847, 477 |
| 5 | 409, 715, 320, 847, 477 |
| 11 | 409, 143, 64, 847, 477 |
| 409, 13, 64, 77, 477 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 409 x 13 x 64 x 77 x 477 = 1374828174720
Therefore, the lowest common multiple of 818,715,640,847,477 is 1374828174720.
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.
818 x 715 x 640 x 847 x 477 = 151231099219200
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.
818 : 1, 2, 409, 818
715 : 1, 5, 11, 13, 55, 65, 143, 715
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
847 : 1, 7, 11, 77, 121, 847
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,715,640,847,477, is 1.
Now, the common factors can be found like this.
818:2x 409
715:5x 11x 13
640:2x 2x 2x 2x 2x 2x 2x 5
847:7x 11x 11
477:3x 3x 53
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 11 = 110
Therefore, the value for common factors is 110.
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 = 151231099219200/(1x110)
LCM = 151231099219200/110
LCM = 1374828174720
Thus, we can understand that the LCM of 818,715,640,847,477 is 1374828174720.
