Find LCM of 776,821,117,997,520 with Prime Factorization
| 2 | 776, 821, 117, 997, 520 |
| 2 | 388, 821, 117, 997, 260 |
| 2 | 194, 821, 117, 997, 130 |
| 13 | 97, 821, 117, 997, 65 |
| 97, 821, 9, 997, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 97 x 821 x 9 x 997 x 5 = 371583056520
Therefore, the lowest common multiple of 776,821,117,997,520 is 371583056520.
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.
776 x 821 x 117 x 997 x 520 = 38644637878080
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.
776 : 1, 2, 4, 8, 97, 194, 388, 776
821 : 1, 821
117 : 1, 3, 9, 13, 39, 117
997 : 1, 997
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,821,117,997,520, is 1.
Now, the common factors can be found like this.
776:2x 2x 2x 97
821:821
117:3x 3x 13
997:997
520:2x 2x 2x 5x 13
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 13 = 104
Therefore, the value for common factors is 104.
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 = 38644637878080/(1x104)
LCM = 38644637878080/104
LCM = 371583056520
Thus, we can understand that the LCM of 776,821,117,997,520 is 371583056520.
