Find LCM of 281,924,686,517,972 with Prime Factorization
| 2 | 281, 924, 686, 517, 972 |
| 2 | 281, 462, 343, 517, 486 |
| 3 | 281, 231, 343, 517, 243 |
| 7 | 281, 77, 343, 517, 81 |
| 11 | 281, 11, 49, 517, 81 |
| 281, 1, 49, 47, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 281 x 1 x 49 x 47 x 81 = 48434770692
Therefore, the lowest common multiple of 281,924,686,517,972 is 48434770692.
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.
281 x 924 x 686 x 517 x 972 = 89507456238816
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.
281 : 1, 281
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
686 : 1, 2, 7, 14, 49, 98, 343, 686
517 : 1, 11, 47, 517
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,924,686,517,972, is 1.
Now, the common factors can be found like this.
281:281
924:2x 2x 3x 7x 11
686:2x 7x 7x 7
517:11x 47
972:2x 2x 3x 3x 3x 3x 3
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 3x 7x 11 = 1848
Therefore, the value for common factors is 1848.
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 = 89507456238816/(1x1848)
LCM = 89507456238816/1848
LCM = 48434770692
Thus, we can understand that the LCM of 281,924,686,517,972 is 48434770692.
