Given numbers are 422,889,390,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,889,390,422 is 73155810.
Find LCM of 422,889,390,422 with Prime Factorization
| 2 | 422, 889, 390, 422 |
| 211 | 211, 889, 195, 211 |
| 1, 889, 195, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 211 x 1 x 889 x 195 x 1 = 73155810
Therefore, the lowest common multiple of 422,889,390,422 is 73155810.
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.
422 x 889 x 390 x 422 = 61743503640
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.
422 : 1, 2, 211, 422
889 : 1, 7, 127, 889
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,889,390,422, is 1.
Now, the common factors can be found like this.
422:2x 211
889:7x 127
390:2x 3x 5x 13
422:2x 211
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 211 = 844
Therefore, the value for common factors is 844.
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 = 61743503640/(1x844)
LCM = 61743503640/844
LCM = 73155810
Thus, we can understand that the LCM of 422,889,390,422 is 73155810.
