Given numbers are 699,438,438,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,438,438,555 is 18879990.
Find LCM of 699,438,438,555 with Prime Factorization
| 2 | 699, 438, 438, 555 |
| 3 | 699, 219, 219, 555 |
| 73 | 233, 73, 73, 185 |
| 233, 1, 1, 185 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 233 x 1 x 1 x 185 = 18879990
Therefore, the lowest common multiple of 699,438,438,555 is 18879990.
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.
699 x 438 x 438 x 555 = 74424920580
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.
699 : 1, 3, 233, 699
438 : 1, 2, 3, 6, 73, 146, 219, 438
438 : 1, 2, 3, 6, 73, 146, 219, 438
555 : 1, 3, 5, 15, 37, 111, 185, 555
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,438,438,555, is 3.
Now, the common factors can be found like this.
699:3x 233
438:2x 3x 73
438:2x 3x 73
555:3x 5x 37
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 3x 73 = 1314
Therefore, the value for common factors is 1314.
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 = 74424920580/(3x1314)
LCM = 74424920580/3942
LCM = 18879990
Thus, we can understand that the LCM of 699,438,438,555 is 18879990.
