The LCM of 528,779,822,685 is 281748720.
Find LCM of 528,779,822,685 with Prime Factorization
| 2 | 528, 779, 822, 685 |
| 3 | 264, 779, 411, 685 |
| 137 | 88, 779, 137, 685 |
| 88, 779, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 88 x 779 x 1 x 5 = 281748720
Therefore, the lowest common multiple of 528,779,822,685 is 281748720.
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.
528 x 779 x 822 x 685 = 231597447840
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.
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
779 : 1, 19, 41, 779
822 : 1, 2, 3, 6, 137, 274, 411, 822
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 528,779,822,685, is 1.
Now, the common factors can be found like this.
528:2x 2x 2x 2x 3x 11
779:19x 41
822:2x 3x 137
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 137 = 822
Therefore, the value for common factors is 822.
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 = 231597447840/(1x822)
LCM = 231597447840/822
LCM = 281748720
Thus, we can understand that the LCM of 528,779,822,685 is 281748720.
