Given numbers are 554,285,639,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 554,285,639,781 is 369936270.
Find LCM of 554,285,639,781 with Prime Factorization
| 3 | 554, 285, 639, 781 |
| 71 | 554, 95, 213, 781 |
| 554, 95, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 71 x 554 x 95 x 3 x 11 = 369936270
Therefore, the lowest common multiple of 554,285,639,781 is 369936270.
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.
554 x 285 x 639 x 781 = 78796425510
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.
554 : 1, 2, 277, 554
285 : 1, 3, 5, 15, 19, 57, 95, 285
639 : 1, 3, 9, 71, 213, 639
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,285,639,781, is 1.
Now, the common factors can be found like this.
554:2x 277
285:3x 5x 19
639:3x 3x 71
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 71 = 213
Therefore, the value for common factors is 213.
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 = 78796425510/(1x213)
LCM = 78796425510/213
LCM = 369936270
Thus, we can understand that the LCM of 554,285,639,781 is 369936270.
