Given numbers are 873,814,639,238,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 873,814,639,238,538 is 1615088179782.
Find LCM of 873,814,639,238,538 with Prime Factorization
| 2 | 873, 814, 639, 238, 538 |
| 3 | 873, 407, 639, 119, 269 |
| 3 | 291, 407, 213, 119, 269 |
| 97, 407, 71, 119, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 97 x 407 x 71 x 119 x 269 = 1615088179782
Therefore, the lowest common multiple of 873,814,639,238,538 is 1615088179782.
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.
873 x 814 x 639 x 238 x 538 = 58143174472152
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.
873 : 1, 3, 9, 97, 291, 873
814 : 1, 2, 11, 22, 37, 74, 407, 814
639 : 1, 3, 9, 71, 213, 639
238 : 1, 2, 7, 14, 17, 34, 119, 238
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,814,639,238,538, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
814:2x 11x 37
639:3x 3x 71
238:2x 7x 17
538:2x 269
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 3 = 36
Therefore, the value for common factors is 36.
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 = 58143174472152/(1x36)
LCM = 58143174472152/36
LCM = 1615088179782
Thus, we can understand that the LCM of 873,814,639,238,538 is 1615088179782.
