Given numbers are 889,686,938,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,686,938,494 is 1441781978.
Find LCM of 889,686,938,494 with Prime Factorization
| 2 | 889, 686, 938, 494 |
| 7 | 889, 343, 469, 247 |
| 127, 49, 67, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 127 x 49 x 67 x 247 = 1441781978
Therefore, the lowest common multiple of 889,686,938,494 is 1441781978.
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.
889 x 686 x 938 x 494 = 282589267688
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.
889 : 1, 7, 127, 889
686 : 1, 2, 7, 14, 49, 98, 343, 686
938 : 1, 2, 7, 14, 67, 134, 469, 938
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 889,686,938,494, is 1.
Now, the common factors can be found like this.
889:7x 127
686:2x 7x 7x 7
938:2x 7x 67
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 2x 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 282589267688/(1x196)
LCM = 282589267688/196
LCM = 1441781978
Thus, we can understand that the LCM of 889,686,938,494 is 1441781978.
