Find LCM of 619,663,858,286,440 with Prime Factorization
2 | 619, 663, 858, 286, 440 |
3 | 619, 663, 429, 143, 220 |
11 | 619, 221, 143, 143, 220 |
13 | 619, 221, 13, 13, 20 |
619, 17, 1, 1, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 619 x 17 x 1 x 1 x 20 = 180574680
Therefore, the lowest common multiple of 619,663,858,286,440 is 180574680.
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.
619 x 663 x 858 x 286 x 440 = 44310859575840
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.
619 : 1, 619
663 : 1, 3, 13, 17, 39, 51, 221, 663
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
286 : 1, 2, 11, 13, 22, 26, 143, 286
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,663,858,286,440, is 1.
Now, the common factors can be found like this.
619:619
663:3x 13x 17
858:2x 3x 11x 13
286:2x 11x 13
440:2x 2x 2x 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 3x 11x 11x 13x 13 = 245388
Therefore, the value for common factors is 245388.
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 = 44310859575840/(1x245388)
LCM = 44310859575840/245388
LCM = 180574680
Thus, we can understand that the LCM of 619,663,858,286,440 is 180574680.
