Find LCM of 902,858,786,221,550 with Prime Factorization
| 2 | 902, 858, 786, 221, 550 |
| 3 | 451, 429, 393, 221, 275 |
| 11 | 451, 143, 131, 221, 275 |
| 13 | 41, 13, 131, 221, 25 |
| 41, 1, 131, 17, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 41 x 1 x 131 x 17 x 25 = 1958535150
Therefore, the lowest common multiple of 902,858,786,221,550 is 1958535150.
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.
902 x 858 x 786 x 221 x 550 = 73938618982800
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
786 : 1, 2, 3, 6, 131, 262, 393, 786
221 : 1, 13, 17, 221
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,858,786,221,550, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
858:2x 3x 11x 13
786:2x 3x 131
221:13x 17
550:2x 5x 5x 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 2x 3x 11x 11x 13 = 37752
Therefore, the value for common factors is 37752.
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 = 73938618982800/(1x37752)
LCM = 73938618982800/37752
LCM = 1958535150
Thus, we can understand that the LCM of 902,858,786,221,550 is 1958535150.
