Find LCM of 680,734,781,935,581 with Prime Factorization
| 2 | 680, 734, 781, 935, 581 |
| 5 | 340, 367, 781, 935, 581 |
| 11 | 68, 367, 781, 187, 581 |
| 17 | 68, 367, 71, 17, 581 |
| 4, 367, 71, 1, 581 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 17 x 4 x 367 x 71 x 1 x 581 = 113240595160
Therefore, the lowest common multiple of 680,734,781,935,581 is 113240595160.
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.
680 x 734 x 781 x 935 x 581 = 211759912949200
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
734 : 1, 2, 367, 734
781 : 1, 11, 71, 781
935 : 1, 5, 11, 17, 55, 85, 187, 935
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,734,781,935,581, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
734:2x 367
781:11x 71
935:5x 11x 17
581:7x 83
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 11x 17 = 1870
Therefore, the value for common factors is 1870.
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 = 211759912949200/(1x1870)
LCM = 211759912949200/1870
LCM = 113240595160
Thus, we can understand that the LCM of 680,734,781,935,581 is 113240595160.
