Find LCM of 919,496,772,330,638 with Prime Factorization
2 | 919, 496, 772, 330, 638 |
2 | 919, 248, 386, 165, 319 |
11 | 919, 124, 193, 165, 319 |
919, 124, 193, 15, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 919 x 124 x 193 x 15 x 29 = 420955743120
Therefore, the lowest common multiple of 919,496,772,330,638 is 420955743120.
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.
919 x 496 x 772 x 330 x 638 = 74088210789120
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.
919 : 1, 919
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
772 : 1, 2, 4, 193, 386, 772
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,496,772,330,638, is 1.
Now, the common factors can be found like this.
919:919
496:2x 2x 2x 2x 31
772:2x 2x 193
330:2x 3x 5x 11
638:2x 11x 29
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 74088210789120/(1x176)
LCM = 74088210789120/176
LCM = 420955743120
Thus, we can understand that the LCM of 919,496,772,330,638 is 420955743120.
