Find LCM of 358,436,861,252,981 with Prime Factorization
| 2 | 358, 436, 861, 252, 981 |
| 2 | 179, 218, 861, 126, 981 |
| 3 | 179, 109, 861, 63, 981 |
| 3 | 179, 109, 287, 21, 327 |
| 7 | 179, 109, 287, 7, 109 |
| 109 | 179, 109, 41, 1, 109 |
| 179, 1, 41, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 109 x 179 x 1 x 41 x 1 x 1 = 201587652
Therefore, the lowest common multiple of 358,436,861,252,981 is 201587652.
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.
358 x 436 x 861 x 252 x 981 = 33223257750816
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.
358 : 1, 2, 179, 358
436 : 1, 2, 4, 109, 218, 436
861 : 1, 3, 7, 21, 41, 123, 287, 861
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,436,861,252,981, is 1.
Now, the common factors can be found like this.
358:2x 179
436:2x 2x 109
861:3x 7x 41
252:2x 2x 3x 3x 7
981:3x 3x 109
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 3x 3x 7x 109 = 164808
Therefore, the value for common factors is 164808.
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 = 33223257750816/(1x164808)
LCM = 33223257750816/164808
LCM = 201587652
Thus, we can understand that the LCM of 358,436,861,252,981 is 201587652.
