Given numbers are 815,558,789,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,558,789,651 is 837231570.
Find LCM of 815,558,789,651 with Prime Factorization
3 | 815, 558, 789, 651 |
31 | 815, 186, 263, 217 |
815, 6, 263, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 815 x 6 x 263 x 7 = 837231570
Therefore, the lowest common multiple of 815,558,789,651 is 837231570.
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.
815 x 558 x 789 x 651 = 233587608030
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.
815 : 1, 5, 163, 815
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
789 : 1, 3, 263, 789
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,558,789,651, is 1.
Now, the common factors can be found like this.
815:5x 163
558:2x 3x 3x 31
789:3x 263
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 31 = 279
Therefore, the value for common factors is 279.
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 = 233587608030/(1x279)
LCM = 233587608030/279
LCM = 837231570
Thus, we can understand that the LCM of 815,558,789,651 is 837231570.
