Given numbers are 431,862,758,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,862,758,654 is 106830246.
Find LCM of 431,862,758,654 with Prime Factorization
2 | 431, 862, 758, 654 |
431 | 431, 431, 379, 327 |
1, 1, 379, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 1 x 1 x 379 x 327 = 106830246
Therefore, the lowest common multiple of 431,862,758,654 is 106830246.
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 862 x 758 x 654 = 184175344104
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
862 : 1, 2, 431, 862
758 : 1, 2, 379, 758
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,862,758,654, is 1.
Now, the common factors can be found like this.
431:431
862:2x 431
758:2x 379
654:2x 3x 109
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 431 = 1724
Therefore, the value for common factors is 1724.
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 = 184175344104/(1x1724)
LCM = 184175344104/1724
LCM = 106830246
Thus, we can understand that the LCM of 431,862,758,654 is 106830246.
