Given numbers are 856,815,710,723,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,815,710,723,351 is 4189998632040.
Find LCM of 856,815,710,723,351 with Prime Factorization
2 | 856, 815, 710, 723, 351 |
3 | 428, 815, 355, 723, 351 |
5 | 428, 815, 355, 241, 117 |
428, 163, 71, 241, 117 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 428 x 163 x 71 x 241 x 117 = 4189998632040
Therefore, the lowest common multiple of 856,815,710,723,351 is 4189998632040.
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.
856 x 815 x 710 x 723 x 351 = 125699958961200
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
815 : 1, 5, 163, 815
710 : 1, 2, 5, 10, 71, 142, 355, 710
723 : 1, 3, 241, 723
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,815,710,723,351, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
815:5x 163
710:2x 5x 71
723:3x 241
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 125699958961200/(1x30)
LCM = 125699958961200/30
LCM = 4189998632040
Thus, we can understand that the LCM of 856,815,710,723,351 is 4189998632040.
