Given numbers are 638,771,788,829
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,771,788,829 is 160666676148.
Find LCM of 638,771,788,829 with Prime Factorization
2 | 638, 771, 788, 829 |
319, 771, 394, 829 |
Multiply the prime numbers at the bottom and the left side.
2 x 319 x 771 x 394 x 829 = 160666676148
Therefore, the lowest common multiple of 638,771,788,829 is 160666676148.
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 771 x 788 x 829 = 321333352296
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
771 : 1, 3, 257, 771
788 : 1, 2, 4, 197, 394, 788
829 : 1, 829
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,771,788,829, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
771:3x 257
788:2x 2x 197
829:829
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 = 321333352296/(1x2)
LCM = 321333352296/2
LCM = 160666676148
Thus, we can understand that the LCM of 638,771,788,829 is 160666676148.
