Given numbers are 717,556,860,538,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,556,860,538,172 is 23056038420.
Find LCM of 717,556,860,538,172 with Prime Factorization
| 2 | 717, 556, 860, 538, 172 |
| 2 | 717, 278, 430, 269, 86 |
| 43 | 717, 139, 215, 269, 43 |
| 717, 139, 5, 269, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 717 x 139 x 5 x 269 x 1 = 23056038420
Therefore, the lowest common multiple of 717,556,860,538,172 is 23056038420.
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.
717 x 556 x 860 x 538 x 172 = 31725108865920
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.
717 : 1, 3, 239, 717
556 : 1, 2, 4, 139, 278, 556
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
538 : 1, 2, 269, 538
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,556,860,538,172, is 1.
Now, the common factors can be found like this.
717:3x 239
556:2x 2x 139
860:2x 2x 5x 43
538:2x 269
172:2x 2x 43
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 2x 2x 2x 43 = 1376
Therefore, the value for common factors is 1376.
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 = 31725108865920/(1x1376)
LCM = 31725108865920/1376
LCM = 23056038420
Thus, we can understand that the LCM of 717,556,860,538,172 is 23056038420.
