Given numbers are 386,924,945,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,924,945,804 is 537670980.
Find LCM of 386,924,945,804 with Prime Factorization
| 2 | 386, 924, 945, 804 |
| 2 | 193, 462, 945, 402 |
| 3 | 193, 231, 945, 201 |
| 7 | 193, 77, 315, 67 |
| 193, 11, 45, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 193 x 11 x 45 x 67 = 537670980
Therefore, the lowest common multiple of 386,924,945,804 is 537670980.
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.
386 x 924 x 945 x 804 = 270986173920
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.
386 : 1, 2, 193, 386
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,924,945,804, is 1.
Now, the common factors can be found like this.
386:2x 193
924:2x 2x 3x 7x 11
945:3x 3x 3x 5x 7
804:2x 2x 3x 67
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 7 = 504
Therefore, the value for common factors is 504.
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 = 270986173920/(1x504)
LCM = 270986173920/504
LCM = 537670980
Thus, we can understand that the LCM of 386,924,945,804 is 537670980.
