Find LCM of 971,981,468,178,436 with Prime Factorization
| 2 | 971, 981, 468, 178, 436 |
| 2 | 971, 981, 234, 89, 218 |
| 3 | 971, 981, 117, 89, 109 |
| 3 | 971, 327, 39, 89, 109 |
| 109 | 971, 109, 13, 89, 109 |
| 971, 1, 13, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 109 x 971 x 1 x 13 x 89 x 1 = 4408406028
Therefore, the lowest common multiple of 971,981,468,178,436 is 4408406028.
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.
971 x 981 x 468 x 178 x 436 = 34597170507744
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.
971 : 1, 971
981 : 1, 3, 9, 109, 327, 981
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
178 : 1, 2, 89, 178
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,981,468,178,436, is 1.
Now, the common factors can be found like this.
971:971
981:3x 3x 109
468:2x 2x 3x 3x 13
178:2x 89
436:2x 2x 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 109 = 7848
Therefore, the value for common factors is 7848.
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 = 34597170507744/(1x7848)
LCM = 34597170507744/7848
LCM = 4408406028
Thus, we can understand that the LCM of 971,981,468,178,436 is 4408406028.
