Given numbers are 638,115,434,187,274
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,115,434,187,274 is 37080684410.
Find LCM of 638,115,434,187,274 with Prime Factorization
2 | 638, 115, 434, 187, 274 |
11 | 319, 115, 217, 187, 137 |
29, 115, 217, 17, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 115 x 217 x 17 x 137 = 37080684410
Therefore, the lowest common multiple of 638,115,434,187,274 is 37080684410.
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 115 x 434 x 187 x 274 = 1631550114040
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
115 : 1, 5, 23, 115
434 : 1, 2, 7, 14, 31, 62, 217, 434
187 : 1, 11, 17, 187
274 : 1, 2, 137, 274
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,115,434,187,274, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
115:5x 23
434:2x 7x 31
187:11x 17
274:2x 137
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 11 = 44
Therefore, the value for common factors is 44.
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 = 1631550114040/(1x44)
LCM = 1631550114040/44
LCM = 37080684410
Thus, we can understand that the LCM of 638,115,434,187,274 is 37080684410.
