Given numbers are 431,402,624,818,449
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,402,624,818,449 is 3309072721968.
Find LCM of 431,402,624,818,449 with Prime Factorization
2 | 431, 402, 624, 818, 449 |
3 | 431, 201, 312, 409, 449 |
431, 67, 104, 409, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 431 x 67 x 104 x 409 x 449 = 3309072721968
Therefore, the lowest common multiple of 431,402,624,818,449 is 3309072721968.
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.
431 x 402 x 624 x 818 x 449 = 39708872663616
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.
431 : 1, 431
402 : 1, 2, 3, 6, 67, 134, 201, 402
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
818 : 1, 2, 409, 818
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,402,624,818,449, is 1.
Now, the common factors can be found like this.
431:431
402:2x 3x 67
624:2x 2x 2x 2x 3x 13
818:2x 409
449:449
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 3 = 12
Therefore, the value for common factors is 12.
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 = 39708872663616/(1x12)
LCM = 39708872663616/12
LCM = 3309072721968
Thus, we can understand that the LCM of 431,402,624,818,449 is 3309072721968.
