Given numbers are 890,218,961,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,218,961,431 is 40180668910.
Find LCM of 890,218,961,431 with Prime Factorization
| 2 | 890, 218, 961, 431 |
| 445, 109, 961, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 445 x 109 x 961 x 431 = 40180668910
Therefore, the lowest common multiple of 890,218,961,431 is 40180668910.
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.
890 x 218 x 961 x 431 = 80361337820
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
218 : 1, 2, 109, 218
961 : 1, 31, 961
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,218,961,431, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
218:2x 109
961:31x 31
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 80361337820/(1x2)
LCM = 80361337820/2
LCM = 40180668910
Thus, we can understand that the LCM of 890,218,961,431 is 40180668910.
