Given numbers are 821,606,986,510
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,606,986,510 is 1226401590.
Find LCM of 821,606,986,510 with Prime Factorization
| 2 | 821, 606, 986, 510 |
| 3 | 821, 303, 493, 255 |
| 17 | 821, 101, 493, 85 |
| 821, 101, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 821 x 101 x 29 x 5 = 1226401590
Therefore, the lowest common multiple of 821,606,986,510 is 1226401590.
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 606 x 986 x 510 = 250185924360
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
606 : 1, 2, 3, 6, 101, 202, 303, 606
986 : 1, 2, 17, 29, 34, 58, 493, 986
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,606,986,510, is 1.
Now, the common factors can be found like this.
821:821
606:2x 3x 101
986:2x 17x 29
510:2x 3x 5x 17
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 17 = 204
Therefore, the value for common factors is 204.
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 = 250185924360/(1x204)
LCM = 250185924360/204
LCM = 1226401590
Thus, we can understand that the LCM of 821,606,986,510 is 1226401590.
