Find LCM of 636,768,392,119 with Prime Factorization
| 2 | 636, 768, 392, 119 |
| 2 | 318, 384, 196, 119 |
| 2 | 159, 192, 98, 119 |
| 3 | 159, 96, 49, 119 |
| 7 | 53, 32, 49, 119 |
| 53, 32, 7, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 53 x 32 x 7 x 17 = 33906432
Therefore, the lowest common multiple of 636,768,392,119 is 33906432.
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.
636 x 768 x 392 x 119 = 22785122304
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
119 : 1, 7, 17, 119
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,768,392,119, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
768:2x 2x 2x 2x 2x 2x 2x 2x 3
392:2x 2x 2x 7x 7
119:7x 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 2x 2x 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 22785122304/(1x672)
LCM = 22785122304/672
LCM = 33906432
Thus, we can understand that the LCM of 636,768,392,119 is 33906432.
