Given numbers are 428,278,612,929
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,278,612,929 is 8456014404.
Find LCM of 428,278,612,929 with Prime Factorization
| 2 | 428, 278, 612, 929 |
| 2 | 214, 139, 306, 929 |
| 107, 139, 153, 929 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 107 x 139 x 153 x 929 = 8456014404
Therefore, the lowest common multiple of 428,278,612,929 is 8456014404.
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.
428 x 278 x 612 x 929 = 67648115232
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.
428 : 1, 2, 4, 107, 214, 428
278 : 1, 2, 139, 278
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
929 : 1, 929
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,278,612,929, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
278:2x 139
612:2x 2x 3x 3x 17
929:929
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 2 = 8
Therefore, the value for common factors is 8.
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 = 67648115232/(1x8)
LCM = 67648115232/8
LCM = 8456014404
Thus, we can understand that the LCM of 428,278,612,929 is 8456014404.
