The LCM of 763,218,448,219,389 is 4160046912.
Find LCM of 763,218,448,219,389 with Prime Factorization
| 2 | 763, 218, 448, 219, 389 |
| 7 | 763, 109, 224, 219, 389 |
| 109 | 109, 109, 32, 219, 389 |
| 1, 1, 32, 219, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 109 x 1 x 1 x 32 x 219 x 389 = 4160046912
Therefore, the lowest common multiple of 763,218,448,219,389 is 4160046912.
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.
763 x 218 x 448 x 219 x 389 = 6348231587712
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.
763 : 1, 7, 109, 763
218 : 1, 2, 109, 218
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
219 : 1, 3, 73, 219
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,218,448,219,389, is 1.
Now, the common factors can be found like this.
763:7x 109
218:2x 109
448:2x 2x 2x 2x 2x 2x 7
219:3x 73
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 109 = 1526
Therefore, the value for common factors is 1526.
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 = 6348231587712/(1x1526)
LCM = 6348231587712/1526
LCM = 4160046912
Thus, we can understand that the LCM of 763,218,448,219,389 is 4160046912.
