Given numbers are 511,803,561,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 511,803,561,688 is 197229648.
Find LCM of 511,803,561,688 with Prime Factorization
| 11 | 511, 803, 561, 688 |
| 73 | 511, 73, 51, 688 |
| 7, 1, 51, 688 |
Multiply the prime numbers at the bottom and the left side.
11 x 73 x 7 x 1 x 51 x 688 = 197229648
Therefore, the lowest common multiple of 511,803,561,688 is 197229648.
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.
511 x 803 x 561 x 688 = 158375407344
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.
511 : 1, 7, 73, 511
803 : 1, 11, 73, 803
561 : 1, 3, 11, 17, 33, 51, 187, 561
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,803,561,688, is 1.
Now, the common factors can be found like this.
511:7x 73
803:11x 73
561:3x 11x 17
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 73 = 803
Therefore, the value for common factors is 803.
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 = 158375407344/(1x803)
LCM = 158375407344/803
LCM = 197229648
Thus, we can understand that the LCM of 511,803,561,688 is 197229648.
