Find LCM of 698,550,731,858,387 with Prime Factorization
2 | 698, 550, 731, 858, 387 |
3 | 349, 275, 731, 429, 387 |
11 | 349, 275, 731, 143, 129 |
43 | 349, 25, 731, 13, 129 |
349, 25, 17, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 349 x 25 x 17 x 13 x 3 = 16416907650
Therefore, the lowest common multiple of 698,550,731,858,387 is 16416907650.
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.
698 x 550 x 731 x 858 x 387 = 93182367821400
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.
698 : 1, 2, 349, 698
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
731 : 1, 17, 43, 731
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,550,731,858,387, is 1.
Now, the common factors can be found like this.
698:2x 349
550:2x 5x 5x 11
731:17x 43
858:2x 3x 11x 13
387:3x 3x 43
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 11x 43 = 5676
Therefore, the value for common factors is 5676.
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 = 93182367821400/(1x5676)
LCM = 93182367821400/5676
LCM = 16416907650
Thus, we can understand that the LCM of 698,550,731,858,387 is 16416907650.
