Given numbers are 862,921,718,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,921,718,431 is 285010818.
Find LCM of 862,921,718,431 with Prime Factorization
| 2 | 862, 921, 718, 431 |
| 431 | 431, 921, 359, 431 |
| 1, 921, 359, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 1 x 921 x 359 x 1 = 285010818
Therefore, the lowest common multiple of 862,921,718,431 is 285010818.
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.
862 x 921 x 718 x 431 = 245679325116
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.
862 : 1, 2, 431, 862
921 : 1, 3, 307, 921
718 : 1, 2, 359, 718
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,921,718,431, is 1.
Now, the common factors can be found like this.
862:2x 431
921:3x 307
718:2x 359
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 431 = 862
Therefore, the value for common factors is 862.
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 = 245679325116/(1x862)
LCM = 245679325116/862
LCM = 285010818
Thus, we can understand that the LCM of 862,921,718,431 is 285010818.
