Given numbers are 437,319,505,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,319,505,638 is 140797030.
Find LCM of 437,319,505,638 with Prime Factorization
| 11 | 437, 319, 505, 638 |
| 29 | 437, 29, 505, 58 |
| 437, 1, 505, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 29 x 437 x 1 x 505 x 2 = 140797030
Therefore, the lowest common multiple of 437,319,505,638 is 140797030.
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.
437 x 319 x 505 x 638 = 44914252570
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.
437 : 1, 19, 23, 437
319 : 1, 11, 29, 319
505 : 1, 5, 101, 505
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,319,505,638, is 1.
Now, the common factors can be found like this.
437:19x 23
319:11x 29
505:5x 101
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 29 = 319
Therefore, the value for common factors is 319.
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 = 44914252570/(1x319)
LCM = 44914252570/319
LCM = 140797030
Thus, we can understand that the LCM of 437,319,505,638 is 140797030.
