Given numbers are 902,802,287,553,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,802,287,553,818 is 81808673254.
Find LCM of 902,802,287,553,818 with Prime Factorization
| 2 | 902, 802, 287, 553, 818 |
| 7 | 451, 401, 287, 553, 409 |
| 41 | 451, 401, 41, 79, 409 |
| 11, 401, 1, 79, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 11 x 401 x 1 x 79 x 409 = 81808673254
Therefore, the lowest common multiple of 902,802,287,553,818 is 81808673254.
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.
902 x 802 x 287 x 553 x 818 = 93916356895592
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
802 : 1, 2, 401, 802
287 : 1, 7, 41, 287
553 : 1, 7, 79, 553
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,802,287,553,818, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
802:2x 401
287:7x 41
553:7x 79
818:2x 409
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 7x 41 = 1148
Therefore, the value for common factors is 1148.
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 = 93916356895592/(1x1148)
LCM = 93916356895592/1148
LCM = 81808673254
Thus, we can understand that the LCM of 902,802,287,553,818 is 81808673254.
