Given numbers are 824,533,638,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,533,638,720 is 12609202320.
Find LCM of 824,533,638,720 with Prime Factorization
| 2 | 824, 533, 638, 720 |
| 2 | 412, 533, 319, 360 |
| 2 | 206, 533, 319, 180 |
| 103, 533, 319, 90 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 103 x 533 x 319 x 90 = 12609202320
Therefore, the lowest common multiple of 824,533,638,720 is 12609202320.
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.
824 x 533 x 638 x 720 = 201747237120
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
533 : 1, 13, 41, 533
638 : 1, 2, 11, 22, 29, 58, 319, 638
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,533,638,720, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
533:13x 41
638:2x 11x 29
720:2x 2x 2x 2x 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.
2x 2x 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 201747237120/(1x16)
LCM = 201747237120/16
LCM = 12609202320
Thus, we can understand that the LCM of 824,533,638,720 is 12609202320.
