Find LCM of 785,116,103,356,515 with Prime Factorization
| 2 | 785, 116, 103, 356, 515 |
| 2 | 785, 58, 103, 178, 515 |
| 5 | 785, 29, 103, 89, 515 |
| 103 | 157, 29, 103, 89, 103 |
| 157, 29, 1, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 103 x 157 x 29 x 1 x 89 x 1 = 834747020
Therefore, the lowest common multiple of 785,116,103,356,515 is 834747020.
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.
785 x 116 x 103 x 356 x 515 = 1719578861200
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.
785 : 1, 5, 157, 785
116 : 1, 2, 4, 29, 58, 116
103 : 1, 103
356 : 1, 2, 4, 89, 178, 356
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,116,103,356,515, is 1.
Now, the common factors can be found like this.
785:5x 157
116:2x 2x 29
103:103
356:2x 2x 89
515:5x 103
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 5x 103 = 2060
Therefore, the value for common factors is 2060.
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 = 1719578861200/(1x2060)
LCM = 1719578861200/2060
LCM = 834747020
Thus, we can understand that the LCM of 785,116,103,356,515 is 834747020.
