Find LCM of 221,178,624,891,836 with Prime Factorization
2 | 221, 178, 624, 891, 836 |
2 | 221, 89, 312, 891, 418 |
3 | 221, 89, 156, 891, 209 |
11 | 221, 89, 52, 297, 209 |
13 | 221, 89, 52, 27, 19 |
17, 89, 4, 27, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 17 x 89 x 4 x 27 x 19 = 5327624016
Therefore, the lowest common multiple of 221,178,624,891,836 is 5327624016.
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.
221 x 178 x 624 x 891 x 836 = 18284405622912
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.
221 : 1, 13, 17, 221
178 : 1, 2, 89, 178
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,178,624,891,836, is 1.
Now, the common factors can be found like this.
221:13x 17
178:2x 89
624:2x 2x 2x 2x 3x 13
891:3x 3x 3x 3x 11
836:2x 2x 11x 19
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 3x 11x 13 = 3432
Therefore, the value for common factors is 3432.
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 = 18284405622912/(1x3432)
LCM = 18284405622912/3432
LCM = 5327624016
Thus, we can understand that the LCM of 221,178,624,891,836 is 5327624016.
