The LCM of 504,942,458,785 is 90601560.
Find LCM of 504,942,458,785 with Prime Factorization
| 2 | 504, 942, 458, 785 |
| 3 | 252, 471, 229, 785 |
| 157 | 84, 157, 229, 785 |
| 84, 1, 229, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 84 x 1 x 229 x 5 = 90601560
Therefore, the lowest common multiple of 504,942,458,785 is 90601560.
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.
504 x 942 x 458 x 785 = 170693339040
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
942 : 1, 2, 3, 6, 157, 314, 471, 942
458 : 1, 2, 229, 458
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,942,458,785, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
942:2x 3x 157
458:2x 229
785:5x 157
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 3x 157 = 1884
Therefore, the value for common factors is 1884.
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 = 170693339040/(1x1884)
LCM = 170693339040/1884
LCM = 90601560
Thus, we can understand that the LCM of 504,942,458,785 is 90601560.
