Given numbers are 779,428,247,154,344
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,428,247,154,344 is 28702105432.
Find LCM of 779,428,247,154,344 with Prime Factorization
| 2 | 779, 428, 247, 154, 344 |
| 2 | 779, 214, 247, 77, 172 |
| 19 | 779, 107, 247, 77, 86 |
| 41, 107, 13, 77, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 41 x 107 x 13 x 77 x 86 = 28702105432
Therefore, the lowest common multiple of 779,428,247,154,344 is 28702105432.
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 428 x 247 x 154 x 344 = 4362720025664
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
428 : 1, 2, 4, 107, 214, 428
247 : 1, 13, 19, 247
154 : 1, 2, 7, 11, 14, 22, 77, 154
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,428,247,154,344, is 1.
Now, the common factors can be found like this.
779:19x 41
428:2x 2x 107
247:13x 19
154:2x 7x 11
344:2x 2x 2x 43
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 2x 19 = 152
Therefore, the value for common factors is 152.
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 = 4362720025664/(1x152)
LCM = 4362720025664/152
LCM = 28702105432
Thus, we can understand that the LCM of 779,428,247,154,344 is 28702105432.
