Given numbers are 768,552,764,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,552,764,918 is 516195072.
Find LCM of 768,552,764,918 with Prime Factorization
| 2 | 768, 552, 764, 918 |
| 2 | 384, 276, 382, 459 |
| 2 | 192, 138, 191, 459 |
| 3 | 96, 69, 191, 459 |
| 32, 23, 191, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 32 x 23 x 191 x 153 = 516195072
Therefore, the lowest common multiple of 768,552,764,918 is 516195072.
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.
768 x 552 x 764 x 918 = 297328361472
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
764 : 1, 2, 4, 191, 382, 764
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,552,764,918, is 2.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
552:2x 2x 2x 3x 23
764:2x 2x 191
918:2x 3x 3x 3x 17
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 2x 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 297328361472/(2x288)
LCM = 297328361472/576
LCM = 516195072
Thus, we can understand that the LCM of 768,552,764,918 is 516195072.
