The LCM of 781,564,234,811,724 is 2521704386916.
Find LCM of 781,564,234,811,724 with Prime Factorization
| 2 | 781, 564, 234, 811, 724 |
| 2 | 781, 282, 117, 811, 362 |
| 3 | 781, 141, 117, 811, 181 |
| 781, 47, 39, 811, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 781 x 47 x 39 x 811 x 181 = 2521704386916
Therefore, the lowest common multiple of 781,564,234,811,724 is 2521704386916.
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 564 x 234 x 811 x 724 = 60520905285984
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
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
811 : 1, 811
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,564,234,811,724, is 1.
Now, the common factors can be found like this.
781:11x 71
564:2x 2x 3x 47
234:2x 3x 3x 13
811:811
724:2x 2x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 60520905285984/(1x24)
LCM = 60520905285984/24
LCM = 2521704386916
Thus, we can understand that the LCM of 781,564,234,811,724 is 2521704386916.
