Given numbers are 7,705,871,603
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,705,871,603 is 12895155.
Find LCM of 7,705,871,603 with Prime Factorization
| 3 | 7, 705, 871, 603 |
| 67 | 7, 235, 871, 201 |
| 7, 235, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 67 x 7 x 235 x 13 x 3 = 12895155
Therefore, the lowest common multiple of 7,705,871,603 is 12895155.
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.
7 x 705 x 871 x 603 = 2591926155
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.
7 : 1, 7
705 : 1, 3, 5, 15, 47, 141, 235, 705
871 : 1, 13, 67, 871
603 : 1, 3, 9, 67, 201, 603
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,705,871,603, is 1.
Now, the common factors can be found like this.
7:7
705:3x 5x 47
871:13x 67
603:3x 3x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 67 = 201
Therefore, the value for common factors is 201.
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 = 2591926155/(1x201)
LCM = 2591926155/201
LCM = 12895155
Thus, we can understand that the LCM of 7,705,871,603 is 12895155.
