Find LCM of 945,644,942,931,314 with Prime Factorization
| 2 | 945, 644, 942, 931, 314 |
| 3 | 945, 322, 471, 931, 157 |
| 7 | 315, 322, 157, 931, 157 |
| 157 | 45, 46, 157, 133, 157 |
| 45, 46, 1, 133, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 157 x 45 x 46 x 1 x 133 x 1 = 1815394140
Therefore, the lowest common multiple of 945,644,942,931,314 is 1815394140.
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.
945 x 644 x 942 x 931 x 314 = 167589925428240
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
942 : 1, 2, 3, 6, 157, 314, 471, 942
931 : 1, 7, 19, 49, 133, 931
314 : 1, 2, 157, 314
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,644,942,931,314, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
644:2x 2x 7x 23
942:2x 3x 157
931:7x 7x 19
314:2x 157
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 7x 7x 157 = 92316
Therefore, the value for common factors is 92316.
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 = 167589925428240/(1x92316)
LCM = 167589925428240/92316
LCM = 1815394140
Thus, we can understand that the LCM of 945,644,942,931,314 is 1815394140.
