Find LCM of 378,913,210,681,865 with Prime Factorization
| 2 | 378, 913, 210, 681, 865 |
| 3 | 189, 913, 105, 681, 865 |
| 5 | 63, 913, 35, 227, 865 |
| 7 | 63, 913, 7, 227, 173 |
| 9, 913, 1, 227, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 9 x 913 x 1 x 227 x 173 = 67764859470
Therefore, the lowest common multiple of 378,913,210,681,865 is 67764859470.
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.
378 x 913 x 210 x 681 x 865 = 42691861466100
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
913 : 1, 11, 83, 913
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
681 : 1, 3, 227, 681
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,913,210,681,865, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
913:11x 83
210:2x 3x 5x 7
681:3x 227
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 42691861466100/(1x630)
LCM = 42691861466100/630
LCM = 67764859470
Thus, we can understand that the LCM of 378,913,210,681,865 is 67764859470.
