Given numbers are 815,808,147,764,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,808,147,764,346 is 3198643024920.
Find LCM of 815,808,147,764,346 with Prime Factorization
2 | 815, 808, 147, 764, 346 |
2 | 815, 404, 147, 382, 173 |
815, 202, 147, 191, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 815 x 202 x 147 x 191 x 173 = 3198643024920
Therefore, the lowest common multiple of 815,808,147,764,346 is 3198643024920.
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 808 x 147 x 764 x 346 = 25589144199360
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
147 : 1, 3, 7, 21, 49, 147
764 : 1, 2, 4, 191, 382, 764
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,808,147,764,346, is 1.
Now, the common factors can be found like this.
815:5x 163
808:2x 2x 2x 101
147:3x 7x 7
764:2x 2x 191
346:2x 173
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 2 = 8
Therefore, the value for common factors is 8.
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 = 25589144199360/(1x8)
LCM = 25589144199360/8
LCM = 3198643024920
Thus, we can understand that the LCM of 815,808,147,764,346 is 3198643024920.
