The LCM of 957,154,892,742 is 316701924.
Find LCM of 957,154,892,742 with Prime Factorization
| 2 | 957, 154, 892, 742 |
| 7 | 957, 77, 446, 371 |
| 11 | 957, 11, 446, 53 |
| 87, 1, 446, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 87 x 1 x 446 x 53 = 316701924
Therefore, the lowest common multiple of 957,154,892,742 is 316701924.
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.
957 x 154 x 892 x 742 = 97544192592
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
154 : 1, 2, 7, 11, 14, 22, 77, 154
892 : 1, 2, 4, 223, 446, 892
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,154,892,742, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
154:2x 7x 11
892:2x 2x 223
742:2x 7x 53
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 97544192592/(1x308)
LCM = 97544192592/308
LCM = 316701924
Thus, we can understand that the LCM of 957,154,892,742 is 316701924.
