Given numbers are 629,772,532,831,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,772,532,831,782 is 1234378778052.
Find LCM of 629,772,532,831,782 with Prime Factorization
| 2 | 629, 772, 532, 831, 782 |
| 2 | 629, 386, 266, 831, 391 |
| 17 | 629, 193, 133, 831, 391 |
| 37, 193, 133, 831, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 37 x 193 x 133 x 831 x 23 = 1234378778052
Therefore, the lowest common multiple of 629,772,532,831,782 is 1234378778052.
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.
629 x 772 x 532 x 831 x 782 = 167875513815072
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.
629 : 1, 17, 37, 629
772 : 1, 2, 4, 193, 386, 772
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
831 : 1, 3, 277, 831
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,772,532,831,782, is 1.
Now, the common factors can be found like this.
629:17x 37
772:2x 2x 193
532:2x 2x 7x 19
831:3x 277
782:2x 17x 23
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 17 = 136
Therefore, the value for common factors is 136.
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 = 167875513815072/(1x136)
LCM = 167875513815072/136
LCM = 1234378778052
Thus, we can understand that the LCM of 629,772,532,831,782 is 1234378778052.
