Given numbers are 373,245,605,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 373,245,605,638 is 641339930.
Find LCM of 373,245,605,638 with Prime Factorization
| 5 | 373, 245, 605, 638 |
| 11 | 373, 49, 121, 638 |
| 373, 49, 11, 58 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 373 x 49 x 11 x 58 = 641339930
Therefore, the lowest common multiple of 373,245,605,638 is 641339930.
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.
373 x 245 x 605 x 638 = 35273696150
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.
373 : 1, 373
245 : 1, 5, 7, 35, 49, 245
605 : 1, 5, 11, 55, 121, 605
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 373,245,605,638, is 1.
Now, the common factors can be found like this.
373:373
245:5x 7x 7
605:5x 11x 11
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 35273696150/(1x55)
LCM = 35273696150/55
LCM = 641339930
Thus, we can understand that the LCM of 373,245,605,638 is 641339930.
