Find LCM of 773,747,821,432,664 with Prime Factorization
| 2 | 773, 747, 821, 432, 664 |
| 2 | 773, 747, 821, 216, 332 |
| 2 | 773, 747, 821, 108, 166 |
| 3 | 773, 747, 821, 54, 83 |
| 3 | 773, 249, 821, 18, 83 |
| 83 | 773, 83, 821, 6, 83 |
| 773, 1, 821, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 83 x 773 x 1 x 821 x 6 x 1 = 22755400848
Therefore, the lowest common multiple of 773,747,821,432,664 is 22755400848.
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.
773 x 747 x 821 x 432 x 664 = 135986275467648
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.
773 : 1, 773
747 : 1, 3, 9, 83, 249, 747
821 : 1, 821
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,747,821,432,664, is 1.
Now, the common factors can be found like this.
773:773
747:3x 3x 83
821:821
432:2x 2x 2x 2x 3x 3x 3
664:2x 2x 2x 83
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 83 = 5976
Therefore, the value for common factors is 5976.
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 = 135986275467648/(1x5976)
LCM = 135986275467648/5976
LCM = 22755400848
Thus, we can understand that the LCM of 773,747,821,432,664 is 22755400848.
