Given numbers are 282,874,221,667,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,874,221,667,782 is 789806706.
Find LCM of 282,874,221,667,782 with Prime Factorization
| 2 | 282, 874, 221, 667, 782 |
| 17 | 141, 437, 221, 667, 391 |
| 23 | 141, 437, 13, 667, 23 |
| 141, 19, 13, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 141 x 19 x 13 x 29 x 1 = 789806706
Therefore, the lowest common multiple of 282,874,221,667,782 is 789806706.
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.
282 x 874 x 221 x 667 x 782 = 28410926828232
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
874 : 1, 2, 19, 23, 38, 46, 437, 874
221 : 1, 13, 17, 221
667 : 1, 23, 29, 667
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,874,221,667,782, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
874:2x 19x 23
221:13x 17
667:23x 29
782:2x 17x 23
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 17x 23x 23 = 35972
Therefore, the value for common factors is 35972.
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 = 28410926828232/(1x35972)
LCM = 28410926828232/35972
LCM = 789806706
Thus, we can understand that the LCM of 282,874,221,667,782 is 789806706.
