Given numbers are 763,812,409,981,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,812,409,981,494 is 80472093156.
Find LCM of 763,812,409,981,494 with Prime Factorization
| 2 | 763, 812, 409, 981, 494 |
| 7 | 763, 406, 409, 981, 247 |
| 109 | 109, 58, 409, 981, 247 |
| 1, 58, 409, 9, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 109 x 1 x 58 x 409 x 9 x 247 = 80472093156
Therefore, the lowest common multiple of 763,812,409,981,494 is 80472093156.
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.
763 x 812 x 409 x 981 x 494 = 122800414156056
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.
763 : 1, 7, 109, 763
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
409 : 1, 409
981 : 1, 3, 9, 109, 327, 981
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,812,409,981,494, is 1.
Now, the common factors can be found like this.
763:7x 109
812:2x 2x 7x 29
409:409
981:3x 3x 109
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 109 = 1526
Therefore, the value for common factors is 1526.
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 = 122800414156056/(1x1526)
LCM = 122800414156056/1526
LCM = 80472093156
Thus, we can understand that the LCM of 763,812,409,981,494 is 80472093156.
