The LCM of 816,200,785,763 is 2443736400.
Find LCM of 816,200,785,763 with Prime Factorization
| 2 | 816, 200, 785, 763 |
| 2 | 408, 100, 785, 763 |
| 2 | 204, 50, 785, 763 |
| 5 | 102, 25, 785, 763 |
| 102, 5, 157, 763 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 102 x 5 x 157 x 763 = 2443736400
Therefore, the lowest common multiple of 816,200,785,763 is 2443736400.
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.
816 x 200 x 785 x 763 = 97749456000
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
785 : 1, 5, 157, 785
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,200,785,763, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
200:2x 2x 2x 5x 5
785:5x 157
763:7x 109
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 5 = 40
Therefore, the value for common factors is 40.
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 = 97749456000/(1x40)
LCM = 97749456000/40
LCM = 2443736400
Thus, we can understand that the LCM of 816,200,785,763 is 2443736400.
