Find LCM of 287,814,805,621,250 with Prime Factorization
| 2 | 287, 814, 805, 621, 250 |
| 5 | 287, 407, 805, 621, 125 |
| 7 | 287, 407, 161, 621, 25 |
| 23 | 41, 407, 23, 621, 25 |
| 41, 407, 1, 27, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 41 x 407 x 1 x 27 x 25 = 18134597250
Therefore, the lowest common multiple of 287,814,805,621,250 is 18134597250.
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.
287 x 814 x 805 x 621 x 250 = 29196701572500
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.
287 : 1, 7, 41, 287
814 : 1, 2, 11, 22, 37, 74, 407, 814
805 : 1, 5, 7, 23, 35, 115, 161, 805
621 : 1, 3, 9, 23, 27, 69, 207, 621
250 : 1, 2, 5, 10, 25, 50, 125, 250
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,814,805,621,250, is 1.
Now, the common factors can be found like this.
287:7x 41
814:2x 11x 37
805:5x 7x 23
621:3x 3x 3x 23
250:2x 5x 5x 5
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 23 = 1610
Therefore, the value for common factors is 1610.
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 = 29196701572500/(1x1610)
LCM = 29196701572500/1610
LCM = 18134597250
Thus, we can understand that the LCM of 287,814,805,621,250 is 18134597250.
