Given numbers are 284,420,694,362,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 284,420,694,362,261 is 162942712380.
Find LCM of 284,420,694,362,261 with Prime Factorization
| 2 | 284, 420, 694, 362, 261 |
| 2 | 142, 210, 347, 181, 261 |
| 3 | 71, 105, 347, 181, 261 |
| 71, 35, 347, 181, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 71 x 35 x 347 x 181 x 87 = 162942712380
Therefore, the lowest common multiple of 284,420,694,362,261 is 162942712380.
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.
284 x 420 x 694 x 362 x 261 = 7821250194240
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.
284 : 1, 2, 4, 71, 142, 284
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
694 : 1, 2, 347, 694
362 : 1, 2, 181, 362
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,420,694,362,261, is 1.
Now, the common factors can be found like this.
284:2x 2x 71
420:2x 2x 3x 5x 7
694:2x 347
362:2x 181
261:3x 3x 29
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 7821250194240/(1x48)
LCM = 7821250194240/48
LCM = 162942712380
Thus, we can understand that the LCM of 284,420,694,362,261 is 162942712380.
