Given numbers are 987,634,926,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,634,926,634 is 289725954.
Find LCM of 987,634,926,634 with Prime Factorization
| 2 | 987, 634, 926, 634 |
| 317 | 987, 317, 463, 317 |
| 987, 1, 463, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 317 x 987 x 1 x 463 x 1 = 289725954
Therefore, the lowest common multiple of 987,634,926,634 is 289725954.
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.
987 x 634 x 926 x 634 = 367372509672
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
634 : 1, 2, 317, 634
926 : 1, 2, 463, 926
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,634,926,634, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
634:2x 317
926:2x 463
634:2x 317
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 317 = 1268
Therefore, the value for common factors is 1268.
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 = 367372509672/(1x1268)
LCM = 367372509672/1268
LCM = 289725954
Thus, we can understand that the LCM of 987,634,926,634 is 289725954.
