The LCM of 847,605,423,809,545 is 157967884305.
Find LCM of 847,605,423,809,545 with Prime Factorization
| 5 | 847, 605, 423, 809, 545 |
| 11 | 847, 121, 423, 809, 109 |
| 11 | 77, 11, 423, 809, 109 |
| 7, 1, 423, 809, 109 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 11 x 7 x 1 x 423 x 809 x 109 = 157967884305
Therefore, the lowest common multiple of 847,605,423,809,545 is 157967884305.
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.
847 x 605 x 423 x 809 x 545 = 95570570004525
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.
847 : 1, 7, 11, 77, 121, 847
605 : 1, 5, 11, 55, 121, 605
423 : 1, 3, 9, 47, 141, 423
809 : 1, 809
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,605,423,809,545, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
605:5x 11x 11
423:3x 3x 47
809:809
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11 = 605
Therefore, the value for common factors is 605.
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 = 95570570004525/(1x605)
LCM = 95570570004525/605
LCM = 157967884305
Thus, we can understand that the LCM of 847,605,423,809,545 is 157967884305.
