Find LCM of 117,642,984,428,899 with Prime Factorization
| 2 | 117, 642, 984, 428, 899 |
| 2 | 117, 321, 492, 214, 899 |
| 3 | 117, 321, 246, 107, 899 |
| 107 | 39, 107, 82, 107, 899 |
| 39, 1, 82, 1, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 39 x 1 x 82 x 1 x 899 = 3691502568
Therefore, the lowest common multiple of 117,642,984,428,899 is 3691502568.
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.
117 x 642 x 984 x 428 x 899 = 28439335783872
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.
117 : 1, 3, 9, 13, 39, 117
642 : 1, 2, 3, 6, 107, 214, 321, 642
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
428 : 1, 2, 4, 107, 214, 428
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,642,984,428,899, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
642:2x 3x 107
984:2x 2x 2x 3x 41
428:2x 2x 107
899:29x 31
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 3x 3x 107 = 7704
Therefore, the value for common factors is 7704.
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 = 28439335783872/(1x7704)
LCM = 28439335783872/7704
LCM = 3691502568
Thus, we can understand that the LCM of 117,642,984,428,899 is 3691502568.
