Given numbers are 422,289,115,994,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,289,115,994,938 is 467024135830.
Find LCM of 422,289,115,994,938 with Prime Factorization
| 2 | 422, 289, 115, 994, 938 |
| 7 | 211, 289, 115, 497, 469 |
| 211, 289, 115, 71, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 211 x 289 x 115 x 71 x 67 = 467024135830
Therefore, the lowest common multiple of 422,289,115,994,938 is 467024135830.
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 289 x 115 x 994 x 938 = 13076675803240
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
289 : 1, 17, 289
115 : 1, 5, 23, 115
994 : 1, 2, 7, 14, 71, 142, 497, 994
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,289,115,994,938, is 1.
Now, the common factors can be found like this.
422:2x 211
289:17x 17
115:5x 23
994:2x 7x 71
938:2x 7x 67
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 7 = 28
Therefore, the value for common factors is 28.
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 = 13076675803240/(1x28)
LCM = 13076675803240/28
LCM = 467024135830
Thus, we can understand that the LCM of 422,289,115,994,938 is 467024135830.
