The LCM of 973,810,638,385 is 251413470.
Find LCM of 973,810,638,385 with Prime Factorization
| 2 | 973, 810, 638, 385 |
| 5 | 973, 405, 319, 385 |
| 7 | 973, 81, 319, 77 |
| 11 | 139, 81, 319, 11 |
| 139, 81, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 139 x 81 x 29 x 1 = 251413470
Therefore, the lowest common multiple of 973,810,638,385 is 251413470.
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.
973 x 810 x 638 x 385 = 193588371900
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.
973 : 1, 7, 139, 973
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
638 : 1, 2, 11, 22, 29, 58, 319, 638
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,810,638,385, is 1.
Now, the common factors can be found like this.
973:7x 139
810:2x 3x 3x 3x 3x 5
638:2x 11x 29
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 193588371900/(1x770)
LCM = 193588371900/770
LCM = 251413470
Thus, we can understand that the LCM of 973,810,638,385 is 251413470.
