Given numbers are 561,228,778,562,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,228,778,562,917 is 4273677146508.
Find LCM of 561,228,778,562,917 with Prime Factorization
| 2 | 561, 228, 778, 562, 917 |
| 3 | 561, 114, 389, 281, 917 |
| 187, 38, 389, 281, 917 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 187 x 38 x 389 x 281 x 917 = 4273677146508
Therefore, the lowest common multiple of 561,228,778,562,917 is 4273677146508.
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.
561 x 228 x 778 x 562 x 917 = 51284125758096
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
778 : 1, 2, 389, 778
562 : 1, 2, 281, 562
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,228,778,562,917, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
228:2x 2x 3x 19
778:2x 389
562:2x 281
917:7x 131
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 3 = 12
Therefore, the value for common factors is 12.
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 = 51284125758096/(1x12)
LCM = 51284125758096/12
LCM = 4273677146508
Thus, we can understand that the LCM of 561,228,778,562,917 is 4273677146508.
