Given numbers are 781,362,376,208
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,362,376,208 is 1381945136.
Find LCM of 781,362,376,208 with Prime Factorization
| 2 | 781, 362, 376, 208 |
| 2 | 781, 181, 188, 104 |
| 2 | 781, 181, 94, 52 |
| 781, 181, 47, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 781 x 181 x 47 x 26 = 1381945136
Therefore, the lowest common multiple of 781,362,376,208 is 1381945136.
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.
781 x 362 x 376 x 208 = 22111122176
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.
781 : 1, 11, 71, 781
362 : 1, 2, 181, 362
376 : 1, 2, 4, 8, 47, 94, 188, 376
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,362,376,208, is 1.
Now, the common factors can be found like this.
781:11x 71
362:2x 181
376:2x 2x 2x 47
208:2x 2x 2x 2x 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 2 = 16
Therefore, the value for common factors is 16.
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 = 22111122176/(1x16)
LCM = 22111122176/16
LCM = 1381945136
Thus, we can understand that the LCM of 781,362,376,208 is 1381945136.
