Given numbers are 890,525,987,407,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,525,987,407,621 is 370034245350.
Find LCM of 890,525,987,407,621 with Prime Factorization
| 3 | 890, 525, 987, 407, 621 |
| 5 | 890, 175, 329, 407, 207 |
| 7 | 178, 35, 329, 407, 207 |
| 178, 5, 47, 407, 207 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 178 x 5 x 47 x 407 x 207 = 370034245350
Therefore, the lowest common multiple of 890,525,987,407,621 is 370034245350.
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.
890 x 525 x 987 x 407 x 621 = 116560787285250
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
987 : 1, 3, 7, 21, 47, 141, 329, 987
407 : 1, 11, 37, 407
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,525,987,407,621, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
525:3x 5x 5x 7
987:3x 7x 47
407:11x 37
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 116560787285250/(1x315)
LCM = 116560787285250/315
LCM = 370034245350
Thus, we can understand that the LCM of 890,525,987,407,621 is 370034245350.
