Find LCM of 649,767,840,522,392 with Prime Factorization
| 2 | 649, 767, 840, 522, 392 |
| 2 | 649, 767, 420, 261, 196 |
| 2 | 649, 767, 210, 261, 98 |
| 3 | 649, 767, 105, 261, 49 |
| 7 | 649, 767, 35, 87, 49 |
| 59 | 649, 767, 5, 87, 7 |
| 11, 13, 5, 87, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 59 x 11 x 13 x 5 x 87 x 7 = 4316031720
Therefore, the lowest common multiple of 649,767,840,522,392 is 4316031720.
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.
649 x 767 x 840 x 522 x 392 = 85561012817280
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.
649 : 1, 11, 59, 649
767 : 1, 13, 59, 767
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,767,840,522,392, is 1.
Now, the common factors can be found like this.
649:11x 59
767:13x 59
840:2x 2x 2x 3x 5x 7
522:2x 3x 3x 29
392:2x 2x 2x 7x 7
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 3x 7x 59 = 19824
Therefore, the value for common factors is 19824.
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 = 85561012817280/(1x19824)
LCM = 85561012817280/19824
LCM = 4316031720
Thus, we can understand that the LCM of 649,767,840,522,392 is 4316031720.
