The LCM of 821,578,843,935,126 is 462041041770.
Find LCM of 821,578,843,935,126 with Prime Factorization
| 2 | 821, 578, 843, 935, 126 |
| 3 | 821, 289, 843, 935, 63 |
| 17 | 821, 289, 281, 935, 21 |
| 821, 17, 281, 55, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 821 x 17 x 281 x 55 x 21 = 462041041770
Therefore, the lowest common multiple of 821,578,843,935,126 is 462041041770.
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.
821 x 578 x 843 x 935 x 126 = 47128186260540
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.
821 : 1, 821
578 : 1, 2, 17, 34, 289, 578
843 : 1, 3, 281, 843
935 : 1, 5, 11, 17, 55, 85, 187, 935
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,578,843,935,126, is 1.
Now, the common factors can be found like this.
821:821
578:2x 17x 17
843:3x 281
935:5x 11x 17
126:2x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 47128186260540/(1x102)
LCM = 47128186260540/102
LCM = 462041041770
Thus, we can understand that the LCM of 821,578,843,935,126 is 462041041770.
