Given numbers are 638,851,299,333
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,851,299,333 is 63523746.
Find LCM of 638,851,299,333 with Prime Factorization
| 23 | 638, 851, 299, 333 |
| 37 | 638, 37, 13, 333 |
| 638, 1, 13, 9 |
Multiply the prime numbers at the bottom and the left side.
23 x 37 x 638 x 1 x 13 x 9 = 63523746
Therefore, the lowest common multiple of 638,851,299,333 is 63523746.
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 851 x 299 x 333 = 54058707846
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
851 : 1, 23, 37, 851
299 : 1, 13, 23, 299
333 : 1, 3, 9, 37, 111, 333
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,851,299,333, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
851:23x 37
299:13x 23
333:3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 37 = 851
Therefore, the value for common factors is 851.
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 = 54058707846/(1x851)
LCM = 54058707846/851
LCM = 63523746
Thus, we can understand that the LCM of 638,851,299,333 is 63523746.
