Given numbers are 638,421,306,937
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,421,306,937 is 38506477878.
Find LCM of 638,421,306,937 with Prime Factorization
| 2 | 638, 421, 306, 937 |
| 319, 421, 153, 937 |
Multiply the prime numbers at the bottom and the left side.
2 x 319 x 421 x 153 x 937 = 38506477878
Therefore, the lowest common multiple of 638,421,306,937 is 38506477878.
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 421 x 306 x 937 = 77012955756
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
421 : 1, 421
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
937 : 1, 937
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,421,306,937, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
421:421
306:2x 3x 3x 17
937:937
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 77012955756/(1x2)
LCM = 77012955756/2
LCM = 38506477878
Thus, we can understand that the LCM of 638,421,306,937 is 38506477878.
