Given numbers are 781,838,939,319,352
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,838,939,319,352 is 285153446688.
Find LCM of 781,838,939,319,352 with Prime Factorization
| 2 | 781, 838, 939, 319, 352 |
| 11 | 781, 419, 939, 319, 176 |
| 71, 419, 939, 29, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 419 x 939 x 29 x 16 = 285153446688
Therefore, the lowest common multiple of 781,838,939,319,352 is 285153446688.
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 838 x 939 x 319 x 352 = 69007134098496
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
838 : 1, 2, 419, 838
939 : 1, 3, 313, 939
319 : 1, 11, 29, 319
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,838,939,319,352, is 1.
Now, the common factors can be found like this.
781:11x 71
838:2x 419
939:3x 313
319:11x 29
352:2x 2x 2x 2x 2x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 69007134098496/(1x242)
LCM = 69007134098496/242
LCM = 285153446688
Thus, we can understand that the LCM of 781,838,939,319,352 is 285153446688.
