The LCM of 105,820,314,248,785 is 167619480.
Find LCM of 105,820,314,248,785 with Prime Factorization
| 2 | 105, 820, 314, 248, 785 |
| 2 | 105, 410, 157, 124, 785 |
| 5 | 105, 205, 157, 62, 785 |
| 157 | 21, 41, 157, 62, 157 |
| 21, 41, 1, 62, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 157 x 21 x 41 x 1 x 62 x 1 = 167619480
Therefore, the lowest common multiple of 105,820,314,248,785 is 167619480.
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.
105 x 820 x 314 x 248 x 785 = 5263251672000
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
314 : 1, 2, 157, 314
248 : 1, 2, 4, 8, 31, 62, 124, 248
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,820,314,248,785, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
820:2x 2x 5x 41
314:2x 157
248:2x 2x 2x 31
785:5x 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 2x 5x 5x 157 = 31400
Therefore, the value for common factors is 31400.
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 = 5263251672000/(1x31400)
LCM = 5263251672000/31400
LCM = 167619480
Thus, we can understand that the LCM of 105,820,314,248,785 is 167619480.
