Given numbers are 520,788,906,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 520,788,906,430 is 1995428760.
Find LCM of 520,788,906,430 with Prime Factorization
2 | 520, 788, 906, 430 |
2 | 260, 394, 453, 215 |
5 | 130, 197, 453, 215 |
26, 197, 453, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 26 x 197 x 453 x 43 = 1995428760
Therefore, the lowest common multiple of 520,788,906,430 is 1995428760.
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.
520 x 788 x 906 x 430 = 159634300800
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
788 : 1, 2, 4, 197, 394, 788
906 : 1, 2, 3, 6, 151, 302, 453, 906
430 : 1, 2, 5, 10, 43, 86, 215, 430
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,788,906,430, is 2.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
788:2x 2x 197
906:2x 3x 151
430:2x 5x 43
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 5 = 40
Therefore, the value for common factors is 40.
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 = 159634300800/(2x40)
LCM = 159634300800/80
LCM = 1995428760
Thus, we can understand that the LCM of 520,788,906,430 is 1995428760.
