Given numbers are 638,962,603,520,111
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,962,603,520,111 is 3700948680.
Find LCM of 638,962,603,520,111 with Prime Factorization
| 2 | 638, 962, 603, 520, 111 |
| 3 | 319, 481, 603, 260, 111 |
| 13 | 319, 481, 201, 260, 37 |
| 37 | 319, 37, 201, 20, 37 |
| 319, 1, 201, 20, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 37 x 319 x 1 x 201 x 20 x 1 = 3700948680
Therefore, the lowest common multiple of 638,962,603,520,111 is 3700948680.
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.
638 x 962 x 603 x 520 x 111 = 21361875780960
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
962 : 1, 2, 13, 26, 37, 74, 481, 962
603 : 1, 3, 9, 67, 201, 603
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
111 : 1, 3, 37, 111
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,962,603,520,111, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
962:2x 13x 37
603:3x 3x 67
520:2x 2x 2x 5x 13
111:3x 37
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 3x 13x 37 = 5772
Therefore, the value for common factors is 5772.
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 = 21361875780960/(1x5772)
LCM = 21361875780960/5772
LCM = 3700948680
Thus, we can understand that the LCM of 638,962,603,520,111 is 3700948680.
