The LCM of 191,321,785,314,138 is 2213940210.
Find LCM of 191,321,785,314,138 with Prime Factorization
| 2 | 191, 321, 785, 314, 138 |
| 3 | 191, 321, 785, 157, 69 |
| 157 | 191, 107, 785, 157, 23 |
| 191, 107, 5, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 191 x 107 x 5 x 1 x 23 = 2213940210
Therefore, the lowest common multiple of 191,321,785,314,138 is 2213940210.
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.
191 x 321 x 785 x 314 x 138 = 2085531677820
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.
191 : 1, 191
321 : 1, 3, 107, 321
785 : 1, 5, 157, 785
314 : 1, 2, 157, 314
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,321,785,314,138, is 1.
Now, the common factors can be found like this.
191:191
321:3x 107
785:5x 157
314:2x 157
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 157 = 942
Therefore, the value for common factors is 942.
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 = 2085531677820/(1x942)
LCM = 2085531677820/942
LCM = 2213940210
Thus, we can understand that the LCM of 191,321,785,314,138 is 2213940210.
