Find LCM of 731,989,874,178,389 with Prime Factorization
| 2 | 731, 989, 874, 178, 389 |
| 23 | 731, 989, 437, 89, 389 |
| 43 | 731, 43, 19, 89, 389 |
| 17, 1, 19, 89, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 43 x 17 x 1 x 19 x 89 x 389 = 22119149174
Therefore, the lowest common multiple of 731,989,874,178,389 is 22119149174.
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.
731 x 989 x 874 x 178 x 389 = 43751677066172
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.
731 : 1, 17, 43, 731
989 : 1, 23, 43, 989
874 : 1, 2, 19, 23, 38, 46, 437, 874
178 : 1, 2, 89, 178
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,989,874,178,389, is 1.
Now, the common factors can be found like this.
731:17x 43
989:23x 43
874:2x 19x 23
178:2x 89
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 43 = 1978
Therefore, the value for common factors is 1978.
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 = 43751677066172/(1x1978)
LCM = 43751677066172/1978
LCM = 22119149174
Thus, we can understand that the LCM of 731,989,874,178,389 is 22119149174.
