Given numbers are 331,402,136,894,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,402,136,894,221 is 17526394392.
Find LCM of 331,402,136,894,221 with Prime Factorization
| 2 | 331, 402, 136, 894, 221 |
| 3 | 331, 201, 68, 447, 221 |
| 17 | 331, 67, 68, 149, 221 |
| 331, 67, 4, 149, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 331 x 67 x 4 x 149 x 13 = 17526394392
Therefore, the lowest common multiple of 331,402,136,894,221 is 17526394392.
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.
331 x 402 x 136 x 894 x 221 = 3575384455968
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.
331 : 1, 331
402 : 1, 2, 3, 6, 67, 134, 201, 402
136 : 1, 2, 4, 8, 17, 34, 68, 136
894 : 1, 2, 3, 6, 149, 298, 447, 894
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,402,136,894,221, is 1.
Now, the common factors can be found like this.
331:331
402:2x 3x 67
136:2x 2x 2x 17
894:2x 3x 149
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.
2x 2x 3x 17 = 204
Therefore, the value for common factors is 204.
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 = 3575384455968/(1x204)
LCM = 3575384455968/204
LCM = 17526394392
Thus, we can understand that the LCM of 331,402,136,894,221 is 17526394392.
