Find LCM of 984,984,402,915,814 with Prime Factorization
| 2 | 984, 984, 402, 915, 814 |
| 2 | 492, 492, 201, 915, 407 |
| 2 | 246, 246, 201, 915, 407 |
| 3 | 123, 123, 201, 915, 407 |
| 41 | 41, 41, 67, 305, 407 |
| 1, 1, 67, 305, 407 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 1 x 1 x 67 x 305 x 407 = 8183972280
Therefore, the lowest common multiple of 984,984,402,915,814 is 8183972280.
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.
984 x 984 x 402 x 915 x 814 = 289909034046720
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
402 : 1, 2, 3, 6, 67, 134, 201, 402
915 : 1, 3, 5, 15, 61, 183, 305, 915
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,984,402,915,814, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
984:2x 2x 2x 3x 41
402:2x 3x 67
915:3x 5x 61
814:2x 11x 37
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 3x 3x 3x 41 = 35424
Therefore, the value for common factors is 35424.
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 = 289909034046720/(1x35424)
LCM = 289909034046720/35424
LCM = 8183972280
Thus, we can understand that the LCM of 984,984,402,915,814 is 8183972280.
