Given numbers are 532,649,860,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 532,649,860,660 is 222697860.
Find LCM of 532,649,860,660 with Prime Factorization
| 2 | 532, 649, 860, 660 |
| 2 | 266, 649, 430, 330 |
| 5 | 133, 649, 215, 165 |
| 11 | 133, 649, 43, 33 |
| 133, 59, 43, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 133 x 59 x 43 x 3 = 222697860
Therefore, the lowest common multiple of 532,649,860,660 is 222697860.
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.
532 x 649 x 860 x 660 = 195974116800
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.
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
649 : 1, 11, 59, 649
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 532,649,860,660, is 1.
Now, the common factors can be found like this.
532:2x 2x 7x 19
649:11x 59
860:2x 2x 5x 43
660:2x 2x 3x 5x 11
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 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 195974116800/(1x880)
LCM = 195974116800/880
LCM = 222697860
Thus, we can understand that the LCM of 532,649,860,660 is 222697860.
