Given numbers are 781,263,151,928,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,263,151,928,494 is 7109329761248.
Find LCM of 781,263,151,928,494 with Prime Factorization
| 2 | 781, 263, 151, 928, 494 |
| 781, 263, 151, 464, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 781 x 263 x 151 x 464 x 247 = 7109329761248
Therefore, the lowest common multiple of 781,263,151,928,494 is 7109329761248.
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 263 x 151 x 928 x 494 = 14218659522496
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
263 : 1, 263
151 : 1, 151
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,263,151,928,494, is 1.
Now, the common factors can be found like this.
781:11x 71
263:263
151:151
928:2x 2x 2x 2x 2x 29
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 14218659522496/(1x2)
LCM = 14218659522496/2
LCM = 7109329761248
Thus, we can understand that the LCM of 781,263,151,928,494 is 7109329761248.
