Find LCM of 775,658,437,388,644 with Prime Factorization
| 2 | 775, 658, 437, 388, 644 |
| 2 | 775, 329, 437, 194, 322 |
| 7 | 775, 329, 437, 97, 161 |
| 23 | 775, 47, 437, 97, 23 |
| 775, 47, 19, 97, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 775 x 47 x 19 x 97 x 1 = 43232541100
Therefore, the lowest common multiple of 775,658,437,388,644 is 43232541100.
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.
775 x 658 x 437 x 388 x 644 = 55683512936800
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.
775 : 1, 5, 25, 31, 155, 775
658 : 1, 2, 7, 14, 47, 94, 329, 658
437 : 1, 19, 23, 437
388 : 1, 2, 4, 97, 194, 388
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,658,437,388,644, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
658:2x 7x 47
437:19x 23
388:2x 2x 97
644:2x 2x 7x 23
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 7x 23 = 1288
Therefore, the value for common factors is 1288.
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 = 55683512936800/(1x1288)
LCM = 55683512936800/1288
LCM = 43232541100
Thus, we can understand that the LCM of 775,658,437,388,644 is 43232541100.
