The LCM of 605,570,392,847 is 13518120.
Find LCM of 605,570,392,847 with Prime Factorization
| 2 | 605, 570, 392, 847 |
| 5 | 605, 285, 196, 847 |
| 7 | 121, 57, 196, 847 |
| 11 | 121, 57, 28, 121 |
| 11 | 11, 57, 28, 11 |
| 1, 57, 28, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 11 x 1 x 57 x 28 x 1 = 13518120
Therefore, the lowest common multiple of 605,570,392,847 is 13518120.
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.
605 x 570 x 392 x 847 = 114498476400
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.
605 : 1, 5, 11, 55, 121, 605
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,570,392,847, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
570:2x 3x 5x 19
392:2x 2x 2x 7x 7
847:7x 11x 11
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 7x 11x 11 = 8470
Therefore, the value for common factors is 8470.
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 = 114498476400/(1x8470)
LCM = 114498476400/8470
LCM = 13518120
Thus, we can understand that the LCM of 605,570,392,847 is 13518120.
