Find LCM of 315,574,751,984 with Prime Factorization
| 2 | 315, 574, 751, 984 |
| 3 | 315, 287, 751, 492 |
| 7 | 105, 287, 751, 164 |
| 41 | 15, 41, 751, 164 |
| 15, 1, 751, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 15 x 1 x 751 x 4 = 77593320
Therefore, the lowest common multiple of 315,574,751,984 is 77593320.
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.
315 x 574 x 751 x 984 = 133615697040
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
574 : 1, 2, 7, 14, 41, 82, 287, 574
751 : 1, 751
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,574,751,984, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
574:2x 7x 41
751:751
984:2x 2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 41 = 1722
Therefore, the value for common factors is 1722.
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 = 133615697040/(1x1722)
LCM = 133615697040/1722
LCM = 77593320
Thus, we can understand that the LCM of 315,574,751,984 is 77593320.
