Given numbers are 668,860,744,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,860,744,559 is 347273160.
Find LCM of 668,860,744,559 with Prime Factorization
| 2 | 668, 860, 744, 559 |
| 2 | 334, 430, 372, 559 |
| 43 | 167, 215, 186, 559 |
| 167, 5, 186, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 167 x 5 x 186 x 13 = 347273160
Therefore, the lowest common multiple of 668,860,744,559 is 347273160.
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.
668 x 860 x 744 x 559 = 238923934080
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.
668 : 1, 2, 4, 167, 334, 668
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,860,744,559, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
860:2x 2x 5x 43
744:2x 2x 2x 3x 31
559:13x 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 43 = 688
Therefore, the value for common factors is 688.
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 = 238923934080/(1x688)
LCM = 238923934080/688
LCM = 347273160
Thus, we can understand that the LCM of 668,860,744,559 is 347273160.
