Given numbers are 893,578,981,987,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,578,981,987,221 is 46077583734.
Find LCM of 893,578,981,987,221 with Prime Factorization
| 3 | 893, 578, 981, 987, 221 |
| 17 | 893, 578, 327, 329, 221 |
| 47 | 893, 34, 327, 329, 13 |
| 19, 34, 327, 7, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 47 x 19 x 34 x 327 x 7 x 13 = 46077583734
Therefore, the lowest common multiple of 893,578,981,987,221 is 46077583734.
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.
893 x 578 x 981 x 987 x 221 = 110447968210398
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.
893 : 1, 19, 47, 893
578 : 1, 2, 17, 34, 289, 578
981 : 1, 3, 9, 109, 327, 981
987 : 1, 3, 7, 21, 47, 141, 329, 987
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,578,981,987,221, is 1.
Now, the common factors can be found like this.
893:19x 47
578:2x 17x 17
981:3x 3x 109
987:3x 7x 47
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 47 = 2397
Therefore, the value for common factors is 2397.
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 = 110447968210398/(1x2397)
LCM = 110447968210398/2397
LCM = 46077583734
Thus, we can understand that the LCM of 893,578,981,987,221 is 46077583734.
