Given numbers are 815,931,767,590,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,931,767,590,556 is 323576851780.
Find LCM of 815,931,767,590,556 with Prime Factorization
| 2 | 815, 931, 767, 590, 556 |
| 5 | 815, 931, 767, 295, 278 |
| 59 | 163, 931, 767, 59, 278 |
| 163, 931, 13, 1, 278 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 59 x 163 x 931 x 13 x 1 x 278 = 323576851780
Therefore, the lowest common multiple of 815,931,767,590,556 is 323576851780.
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 931 x 767 x 590 x 556 = 190910342550200
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
931 : 1, 7, 19, 49, 133, 931
767 : 1, 13, 59, 767
590 : 1, 2, 5, 10, 59, 118, 295, 590
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,931,767,590,556, is 1.
Now, the common factors can be found like this.
815:5x 163
931:7x 7x 19
767:13x 59
590:2x 5x 59
556:2x 2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 59 = 590
Therefore, the value for common factors is 590.
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 = 190910342550200/(1x590)
LCM = 190910342550200/590
LCM = 323576851780
Thus, we can understand that the LCM of 815,931,767,590,556 is 323576851780.
