The LCM of 376,231,138,420,783 is 2606982840.
Find LCM of 376,231,138,420,783 with Prime Factorization
| 2 | 376, 231, 138, 420, 783 |
| 2 | 188, 231, 69, 210, 783 |
| 3 | 94, 231, 69, 105, 783 |
| 7 | 94, 77, 23, 35, 261 |
| 94, 11, 23, 5, 261 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 94 x 11 x 23 x 5 x 261 = 2606982840
Therefore, the lowest common multiple of 376,231,138,420,783 is 2606982840.
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.
376 x 231 x 138 x 420 x 783 = 3941758054080
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.
376 : 1, 2, 4, 8, 47, 94, 188, 376
231 : 1, 3, 7, 11, 21, 33, 77, 231
138 : 1, 2, 3, 6, 23, 46, 69, 138
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 376,231,138,420,783, is 1.
Now, the common factors can be found like this.
376:2x 2x 2x 47
231:3x 7x 11
138:2x 3x 23
420:2x 2x 3x 5x 7
783:3x 3x 3x 29
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 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 3941758054080/(1x1512)
LCM = 3941758054080/1512
LCM = 2606982840
Thus, we can understand that the LCM of 376,231,138,420,783 is 2606982840.
