The LCM of 868,290,625,462 is 519172500.
Find LCM of 868,290,625,462 with Prime Factorization
| 2 | 868, 290, 625, 462 |
| 5 | 434, 145, 625, 231 |
| 7 | 434, 29, 125, 231 |
| 62, 29, 125, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 62 x 29 x 125 x 33 = 519172500
Therefore, the lowest common multiple of 868,290,625,462 is 519172500.
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.
868 x 290 x 625 x 462 = 72684150000
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
290 : 1, 2, 5, 10, 29, 58, 145, 290
625 : 1, 5, 25, 125, 625
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,290,625,462, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
290:2x 5x 29
625:5x 5x 5x 5
462:2x 3x 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 2x 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 72684150000/(1x140)
LCM = 72684150000/140
LCM = 519172500
Thus, we can understand that the LCM of 868,290,625,462 is 519172500.
