Given numbers are 638,381,338,911
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,381,338,911 is 37424045802.
Find LCM of 638,381,338,911 with Prime Factorization
2 | 638, 381, 338, 911 |
319, 381, 169, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 319 x 381 x 169 x 911 = 37424045802
Therefore, the lowest common multiple of 638,381,338,911 is 37424045802.
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 381 x 338 x 911 = 74848091604
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
381 : 1, 3, 127, 381
338 : 1, 2, 13, 26, 169, 338
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,381,338,911, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
381:3x 127
338:2x 13x 13
911:911
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 = 74848091604/(1x2)
LCM = 74848091604/2
LCM = 37424045802
Thus, we can understand that the LCM of 638,381,338,911 is 37424045802.
