Find LCM of 619,418,988,755,936 with Prime Factorization
| 2 | 619, 418, 988, 755, 936 |
| 2 | 619, 209, 494, 755, 468 |
| 13 | 619, 209, 247, 755, 234 |
| 19 | 619, 209, 19, 755, 18 |
| 619, 11, 1, 755, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 619 x 11 x 1 x 755 x 18 = 91423898280
Therefore, the lowest common multiple of 619,418,988,755,936 is 91423898280.
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.
619 x 418 x 988 x 755 x 936 = 180653623001280
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.
619 : 1, 619
418 : 1, 2, 11, 19, 22, 38, 209, 418
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
755 : 1, 5, 151, 755
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,418,988,755,936, is 1.
Now, the common factors can be found like this.
619:619
418:2x 11x 19
988:2x 2x 13x 19
755:5x 151
936:2x 2x 2x 3x 3x 13
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 180653623001280/(1x1976)
LCM = 180653623001280/1976
LCM = 91423898280
Thus, we can understand that the LCM of 619,418,988,755,936 is 91423898280.
