Find LCM of 628,885,237,884,921 with Prime Factorization
| 2 | 628, 885, 237, 884, 921 |
| 2 | 314, 885, 237, 442, 921 |
| 3 | 157, 885, 237, 221, 921 |
| 157, 295, 79, 221, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 157 x 295 x 79 x 221 x 307 = 2978932447140
Therefore, the lowest common multiple of 628,885,237,884,921 is 2978932447140.
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.
628 x 885 x 237 x 884 x 921 = 107241568097040
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.
628 : 1, 2, 4, 157, 314, 628
885 : 1, 3, 5, 15, 59, 177, 295, 885
237 : 1, 3, 79, 237
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,885,237,884,921, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
885:3x 5x 59
237:3x 79
884:2x 2x 13x 17
921:3x 307
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 3 = 36
Therefore, the value for common factors is 36.
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 = 107241568097040/(1x36)
LCM = 107241568097040/36
LCM = 2978932447140
Thus, we can understand that the LCM of 628,885,237,884,921 is 2978932447140.
