Find LCM of 137,378,954,809,644 with Prime Factorization
| 2 | 137, 378, 954, 809, 644 |
| 3 | 137, 189, 477, 809, 322 |
| 3 | 137, 63, 159, 809, 322 |
| 7 | 137, 21, 53, 809, 322 |
| 137, 3, 53, 809, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 137 x 3 x 53 x 809 x 46 = 102139702812
Therefore, the lowest common multiple of 137,378,954,809,644 is 102139702812.
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.
137 x 378 x 954 x 809 x 644 = 25739205108624
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.
137 : 1, 137
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
809 : 1, 809
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,378,954,809,644, is 1.
Now, the common factors can be found like this.
137:137
378:2x 3x 3x 3x 7
954:2x 3x 3x 53
809:809
644:2x 2x 7x 23
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 25739205108624/(1x252)
LCM = 25739205108624/252
LCM = 102139702812
Thus, we can understand that the LCM of 137,378,954,809,644 is 102139702812.
