Find LCM of 461,943,720,649,820 with Prime Factorization
| 2 | 461, 943, 720, 649, 820 |
| 2 | 461, 943, 360, 649, 410 |
| 5 | 461, 943, 180, 649, 205 |
| 41 | 461, 943, 36, 649, 41 |
| 461, 23, 36, 649, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 461 x 23 x 36 x 649 x 1 = 203137363440
Therefore, the lowest common multiple of 461,943,720,649,820 is 203137363440.
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.
461 x 943 x 720 x 649 x 820 = 166572638020800
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.
461 : 1, 461
943 : 1, 23, 41, 943
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
649 : 1, 11, 59, 649
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,943,720,649,820, is 1.
Now, the common factors can be found like this.
461:461
943:23x 41
720:2x 2x 2x 2x 3x 3x 5
649:11x 59
820:2x 2x 5x 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 2x 5x 41 = 820
Therefore, the value for common factors is 820.
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 = 166572638020800/(1x820)
LCM = 166572638020800/820
LCM = 203137363440
Thus, we can understand that the LCM of 461,943,720,649,820 is 203137363440.
