Given numbers are 645,431,663,593
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,431,663,593 is 36432078735.
Find LCM of 645,431,663,593 with Prime Factorization
3 | 645, 431, 663, 593 |
215, 431, 221, 593 |
Multiply the prime numbers at the bottom and the left side.
3 x 215 x 431 x 221 x 593 = 36432078735
Therefore, the lowest common multiple of 645,431,663,593 is 36432078735.
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.
645 x 431 x 663 x 593 = 109296236205
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
431 : 1, 431
663 : 1, 3, 13, 17, 39, 51, 221, 663
593 : 1, 593
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,431,663,593, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
431:431
663:3x 13x 17
593:593
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 109296236205/(1x3)
LCM = 109296236205/3
LCM = 36432078735
Thus, we can understand that the LCM of 645,431,663,593 is 36432078735.
