Given numbers are 282,774,788,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,774,788,215 is 71664660.
Find LCM of 282,774,788,215 with Prime Factorization
| 2 | 282, 774, 788, 215 |
| 3 | 141, 387, 394, 215 |
| 43 | 47, 129, 394, 215 |
| 47, 3, 394, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 47 x 3 x 394 x 5 = 71664660
Therefore, the lowest common multiple of 282,774,788,215 is 71664660.
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 774 x 788 x 215 = 36978964560
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
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
788 : 1, 2, 4, 197, 394, 788
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,774,788,215, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
774:2x 3x 3x 43
788:2x 2x 197
215:5x 43
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 3x 43 = 516
Therefore, the value for common factors is 516.
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 = 36978964560/(1x516)
LCM = 36978964560/516
LCM = 71664660
Thus, we can understand that the LCM of 282,774,788,215 is 71664660.
