Given numbers are 822,948,540,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,948,540,770 is 450020340.
Find LCM of 822,948,540,770 with Prime Factorization
| 2 | 822, 948, 540, 770 |
| 2 | 411, 474, 270, 385 |
| 3 | 411, 237, 135, 385 |
| 5 | 137, 79, 45, 385 |
| 137, 79, 9, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 137 x 79 x 9 x 77 = 450020340
Therefore, the lowest common multiple of 822,948,540,770 is 450020340.
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.
822 x 948 x 540 x 770 = 324014644800
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
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
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,948,540,770, is 2.
Now, the common factors can be found like this.
822:2x 3x 137
948:2x 2x 3x 79
540:2x 2x 3x 3x 3x 5
770:2x 5x 7x 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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 324014644800/(2x360)
LCM = 324014644800/720
LCM = 450020340
Thus, we can understand that the LCM of 822,948,540,770 is 450020340.
