Given numbers are 781,856,482,187,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,856,482,187,938 is 1284587244248.
Find LCM of 781,856,482,187,938 with Prime Factorization
| 2 | 781, 856, 482, 187, 938 |
| 11 | 781, 428, 241, 187, 469 |
| 71, 428, 241, 17, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 428 x 241 x 17 x 469 = 1284587244248
Therefore, the lowest common multiple of 781,856,482,187,938 is 1284587244248.
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 856 x 482 x 187 x 938 = 56521838746912
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
482 : 1, 2, 241, 482
187 : 1, 11, 17, 187
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,856,482,187,938, is 1.
Now, the common factors can be found like this.
781:11x 71
856:2x 2x 2x 107
482:2x 241
187:11x 17
938:2x 7x 67
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 11 = 44
Therefore, the value for common factors is 44.
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 = 56521838746912/(1x44)
LCM = 56521838746912/44
LCM = 1284587244248
Thus, we can understand that the LCM of 781,856,482,187,938 is 1284587244248.
