Find LCM of 496,480,820,685,972 with Prime Factorization
| 2 | 496, 480, 820, 685, 972 |
| 2 | 248, 240, 410, 685, 486 |
| 2 | 124, 120, 205, 685, 243 |
| 2 | 62, 60, 205, 685, 243 |
| 3 | 31, 30, 205, 685, 243 |
| 5 | 31, 10, 205, 685, 81 |
| 31, 2, 41, 137, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 31 x 2 x 41 x 137 x 81 = 6770057760
Therefore, the lowest common multiple of 496,480,820,685,972 is 6770057760.
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.
496 x 480 x 820 x 685 x 972 = 129985108992000
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.
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
685 : 1, 5, 137, 685
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,480,820,685,972, is 1.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
480:2x 2x 2x 2x 2x 3x 5
820:2x 2x 5x 41
685:5x 137
972:2x 2x 3x 3x 3x 3x 3
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 2x 2x 2x 3x 5x 5 = 19200
Therefore, the value for common factors is 19200.
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 = 129985108992000/(1x19200)
LCM = 129985108992000/19200
LCM = 6770057760
Thus, we can understand that the LCM of 496,480,820,685,972 is 6770057760.
