Given numbers are 921,428,451,496
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,428,451,496 is 22044569712.
Find LCM of 921,428,451,496 with Prime Factorization
2 | 921, 428, 451, 496 |
2 | 921, 214, 451, 248 |
921, 107, 451, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 921 x 107 x 451 x 124 = 22044569712
Therefore, the lowest common multiple of 921,428,451,496 is 22044569712.
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.
921 x 428 x 451 x 496 = 88178278848
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.
921 : 1, 3, 307, 921
428 : 1, 2, 4, 107, 214, 428
451 : 1, 11, 41, 451
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,428,451,496, is 1.
Now, the common factors can be found like this.
921:3x 307
428:2x 2x 107
451:11x 41
496:2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 88178278848/(1x4)
LCM = 88178278848/4
LCM = 22044569712
Thus, we can understand that the LCM of 921,428,451,496 is 22044569712.
