Given numbers are 278,543,781,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,543,781,984 is 19334792136.
Find LCM of 278,543,781,984 with Prime Factorization
| 2 | 278, 543, 781, 984 |
| 3 | 139, 543, 781, 492 |
| 139, 181, 781, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 139 x 181 x 781 x 164 = 19334792136
Therefore, the lowest common multiple of 278,543,781,984 is 19334792136.
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.
278 x 543 x 781 x 984 = 116008752816
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.
278 : 1, 2, 139, 278
543 : 1, 3, 181, 543
781 : 1, 11, 71, 781
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,543,781,984, is 1.
Now, the common factors can be found like this.
278:2x 139
543:3x 181
781:11x 71
984:2x 2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 116008752816/(1x6)
LCM = 116008752816/6
LCM = 19334792136
Thus, we can understand that the LCM of 278,543,781,984 is 19334792136.
