Given numbers are 679,367,756,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 679,367,756,647 is 17412610068.
Find LCM of 679,367,756,647 with Prime Factorization
| 7 | 679, 367, 756, 647 |
| 97, 367, 108, 647 |
Multiply the prime numbers at the bottom and the left side.
7 x 97 x 367 x 108 x 647 = 17412610068
Therefore, the lowest common multiple of 679,367,756,647 is 17412610068.
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.
679 x 367 x 756 x 647 = 121888270476
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.
679 : 1, 7, 97, 679
367 : 1, 367
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,367,756,647, is 1.
Now, the common factors can be found like this.
679:7x 97
367:367
756:2x 2x 3x 3x 3x 7
647:647
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 121888270476/(1x7)
LCM = 121888270476/7
LCM = 17412610068
Thus, we can understand that the LCM of 679,367,756,647 is 17412610068.
