Find LCM of 643,771,832,399,494 with Prime Factorization
2 | 643, 771, 832, 399, 494 |
3 | 643, 771, 416, 399, 247 |
13 | 643, 257, 416, 133, 247 |
19 | 643, 257, 32, 133, 19 |
643, 257, 32, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 643 x 257 x 32 x 7 x 1 = 54858043968
Therefore, the lowest common multiple of 643,771,832,399,494 is 54858043968.
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.
643 x 771 x 832 x 399 x 494 = 81299621160576
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.
643 : 1, 643
771 : 1, 3, 257, 771
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
399 : 1, 3, 7, 19, 21, 57, 133, 399
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,771,832,399,494, is 1.
Now, the common factors can be found like this.
643:643
771:3x 257
832:2x 2x 2x 2x 2x 2x 13
399:3x 7x 19
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 19 = 1482
Therefore, the value for common factors is 1482.
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 = 81299621160576/(1x1482)
LCM = 81299621160576/1482
LCM = 54858043968
Thus, we can understand that the LCM of 643,771,832,399,494 is 54858043968.
