Given numbers are 539,749,309,861,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 539,749,309,861,540 is 131518662660.
Find LCM of 539,749,309,861,540 with Prime Factorization
| 3 | 539, 749, 309, 861, 540 |
| 7 | 539, 749, 103, 287, 180 |
| 77, 107, 103, 41, 180 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 77 x 107 x 103 x 41 x 180 = 131518662660
Therefore, the lowest common multiple of 539,749,309,861,540 is 131518662660.
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.
539 x 749 x 309 x 861 x 540 = 57999730233060
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.
539 : 1, 7, 11, 49, 77, 539
749 : 1, 7, 107, 749
309 : 1, 3, 103, 309
861 : 1, 3, 7, 21, 41, 123, 287, 861
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 539,749,309,861,540, is 1.
Now, the common factors can be found like this.
539:7x 7x 11
749:7x 107
309:3x 103
861:3x 7x 41
540:2x 2x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 7 = 441
Therefore, the value for common factors is 441.
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 = 57999730233060/(1x441)
LCM = 57999730233060/441
LCM = 131518662660
Thus, we can understand that the LCM of 539,749,309,861,540 is 131518662660.
