Given numbers are 432,394,590,638,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 432,394,590,638,916 is 1833995029680.
Find LCM of 432,394,590,638,916 with Prime Factorization
| 2 | 432, 394, 590, 638, 916 |
| 2 | 216, 197, 295, 319, 458 |
| 108, 197, 295, 319, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 108 x 197 x 295 x 319 x 229 = 1833995029680
Therefore, the lowest common multiple of 432,394,590,638,916 is 1833995029680.
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.
432 x 394 x 590 x 638 x 916 = 58687840949760
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
394 : 1, 2, 197, 394
590 : 1, 2, 5, 10, 59, 118, 295, 590
638 : 1, 2, 11, 22, 29, 58, 319, 638
916 : 1, 2, 4, 229, 458, 916
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,394,590,638,916, is 2.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
394:2x 197
590:2x 5x 59
638:2x 11x 29
916:2x 2x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 58687840949760/(2x16)
LCM = 58687840949760/32
LCM = 1833995029680
Thus, we can understand that the LCM of 432,394,590,638,916 is 1833995029680.
