Find LCM of 728,247,984,452,869 with Prime Factorization
| 2 | 728, 247, 984, 452, 869 |
| 2 | 364, 247, 492, 226, 869 |
| 2 | 182, 247, 246, 113, 869 |
| 13 | 91, 247, 123, 113, 869 |
| 7, 19, 123, 113, 869 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 7 x 19 x 123 x 113 x 869 = 167066091192
Therefore, the lowest common multiple of 728,247,984,452,869 is 167066091192.
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.
728 x 247 x 984 x 452 x 869 = 69499493935872
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
247 : 1, 13, 19, 247
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
452 : 1, 2, 4, 113, 226, 452
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,247,984,452,869, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
247:13x 19
984:2x 2x 2x 3x 41
452:2x 2x 113
869:11x 79
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 2x 2x 13 = 416
Therefore, the value for common factors is 416.
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 = 69499493935872/(1x416)
LCM = 69499493935872/416
LCM = 167066091192
Thus, we can understand that the LCM of 728,247,984,452,869 is 167066091192.
