Find LCM of 781,497,690,875,848 with Prime Factorization
| 2 | 781, 497, 690, 875, 848 |
| 5 | 781, 497, 345, 875, 424 |
| 7 | 781, 497, 69, 175, 424 |
| 71 | 781, 71, 69, 25, 424 |
| 11, 1, 69, 25, 424 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 71 x 11 x 1 x 69 x 25 x 424 = 39985638000
Therefore, the lowest common multiple of 781,497,690,875,848 is 39985638000.
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.
781 x 497 x 690 x 875 x 848 = 198728620860000
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.
781 : 1, 11, 71, 781
497 : 1, 7, 71, 497
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
875 : 1, 5, 7, 25, 35, 125, 175, 875
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,497,690,875,848, is 1.
Now, the common factors can be found like this.
781:11x 71
497:7x 71
690:2x 3x 5x 23
875:5x 5x 5x 7
848:2x 2x 2x 2x 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 7x 71 = 4970
Therefore, the value for common factors is 4970.
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 = 198728620860000/(1x4970)
LCM = 198728620860000/4970
LCM = 39985638000
Thus, we can understand that the LCM of 781,497,690,875,848 is 39985638000.
