Given numbers are 946,406,649,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,406,649,442 is 2503983482.
Find LCM of 946,406,649,442 with Prime Factorization
| 2 | 946, 406, 649, 442 |
| 11 | 473, 203, 649, 221 |
| 43, 203, 59, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 203 x 59 x 221 = 2503983482
Therefore, the lowest common multiple of 946,406,649,442 is 2503983482.
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.
946 x 406 x 649 x 442 = 110175273208
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
406 : 1, 2, 7, 14, 29, 58, 203, 406
649 : 1, 11, 59, 649
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,406,649,442, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
406:2x 7x 29
649:11x 59
442:2x 13x 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 11 = 44
Therefore, the value for common factors is 44.
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 = 110175273208/(1x44)
LCM = 110175273208/44
LCM = 2503983482
Thus, we can understand that the LCM of 946,406,649,442 is 2503983482.
