Given numbers are 779,291,642,192
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,291,642,192 is 1552366272.
Find LCM of 779,291,642,192 with Prime Factorization
| 2 | 779, 291, 642, 192 |
| 3 | 779, 291, 321, 96 |
| 779, 97, 107, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 779 x 97 x 107 x 32 = 1552366272
Therefore, the lowest common multiple of 779,291,642,192 is 1552366272.
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.
779 x 291 x 642 x 192 = 27942592896
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.
779 : 1, 19, 41, 779
291 : 1, 3, 97, 291
642 : 1, 2, 3, 6, 107, 214, 321, 642
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,291,642,192, is 1.
Now, the common factors can be found like this.
779:19x 41
291:3x 97
642:2x 3x 107
192:2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 27942592896/(1x18)
LCM = 27942592896/18
LCM = 1552366272
Thus, we can understand that the LCM of 779,291,642,192 is 1552366272.
