Find LCM of 638,895,615,510,272 with Prime Factorization
2 | 638, 895, 615, 510, 272 |
3 | 319, 895, 615, 255, 136 |
5 | 319, 895, 205, 85, 136 |
17 | 319, 179, 41, 17, 136 |
319, 179, 41, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 319 x 179 x 41 x 1 x 8 = 9551855280
Therefore, the lowest common multiple of 638,895,615,510,272 is 9551855280.
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.
638 x 895 x 615 x 510 x 272 = 48714461928000
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
895 : 1, 5, 179, 895
615 : 1, 3, 5, 15, 41, 123, 205, 615
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,895,615,510,272, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
895:5x 179
615:3x 5x 41
510:2x 3x 5x 17
272:2x 2x 2x 2x 17
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 5x 5x 17 = 5100
Therefore, the value for common factors is 5100.
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 = 48714461928000/(1x5100)
LCM = 48714461928000/5100
LCM = 9551855280
Thus, we can understand that the LCM of 638,895,615,510,272 is 9551855280.
