Find LCM of 851,115,208,656,138 with Prime Factorization
2 | 851, 115, 208, 656, 138 |
2 | 851, 115, 104, 328, 69 |
2 | 851, 115, 52, 164, 69 |
2 | 851, 115, 26, 82, 69 |
23 | 851, 115, 13, 41, 69 |
37, 5, 13, 41, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 23 x 37 x 5 x 13 x 41 x 3 = 108859920
Therefore, the lowest common multiple of 851,115,208,656,138 is 108859920.
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.
851 x 115 x 208 x 656 x 138 = 1842780725760
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.
851 : 1, 23, 37, 851
115 : 1, 5, 23, 115
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,115,208,656,138, is 1.
Now, the common factors can be found like this.
851:23x 37
115:5x 23
208:2x 2x 2x 2x 13
656:2x 2x 2x 2x 41
138:2x 3x 23
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 23x 23 = 16928
Therefore, the value for common factors is 16928.
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 = 1842780725760/(1x16928)
LCM = 1842780725760/16928
LCM = 108859920
Thus, we can understand that the LCM of 851,115,208,656,138 is 108859920.
