Given numbers are 262,411,280,639,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,411,280,639,838 is 1345441363560.
Find LCM of 262,411,280,639,838 with Prime Factorization
| 2 | 262, 411, 280, 639, 838 |
| 3 | 131, 411, 140, 639, 419 |
| 131, 137, 140, 213, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 131 x 137 x 140 x 213 x 419 = 1345441363560
Therefore, the lowest common multiple of 262,411,280,639,838 is 1345441363560.
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.
262 x 411 x 280 x 639 x 838 = 16145296362720
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.
262 : 1, 2, 131, 262
411 : 1, 3, 137, 411
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
639 : 1, 3, 9, 71, 213, 639
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,411,280,639,838, is 1.
Now, the common factors can be found like this.
262:2x 131
411:3x 137
280:2x 2x 2x 5x 7
639:3x 3x 71
838:2x 419
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 3 = 12
Therefore, the value for common factors is 12.
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 = 16145296362720/(1x12)
LCM = 16145296362720/12
LCM = 1345441363560
Thus, we can understand that the LCM of 262,411,280,639,838 is 1345441363560.
