Given numbers are 781,542,142,132,266
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,542,142,132,266 is 337794996.
Find LCM of 781,542,142,132,266 with Prime Factorization
| 2 | 781, 542, 142, 132, 266 |
| 11 | 781, 271, 71, 66, 133 |
| 71 | 71, 271, 71, 6, 133 |
| 1, 271, 1, 6, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 1 x 271 x 1 x 6 x 133 = 337794996
Therefore, the lowest common multiple of 781,542,142,132,266 is 337794996.
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 542 x 142 x 132 x 266 = 2110543135008
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
542 : 1, 2, 271, 542
142 : 1, 2, 71, 142
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
266 : 1, 2, 7, 14, 19, 38, 133, 266
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,542,142,132,266, is 1.
Now, the common factors can be found like this.
781:11x 71
542:2x 271
142:2x 71
132:2x 2x 3x 11
266:2x 7x 19
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 11x 71 = 6248
Therefore, the value for common factors is 6248.
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 = 2110543135008/(1x6248)
LCM = 2110543135008/6248
LCM = 337794996
Thus, we can understand that the LCM of 781,542,142,132,266 is 337794996.
