Find LCM of 918,997,493,690,915 with Prime Factorization
| 2 | 918, 997, 493, 690, 915 |
| 3 | 459, 997, 493, 345, 915 |
| 5 | 153, 997, 493, 115, 305 |
| 17 | 153, 997, 493, 23, 61 |
| 9, 997, 29, 23, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 9 x 997 x 29 x 23 x 61 = 186193070010
Therefore, the lowest common multiple of 918,997,493,690,915 is 186193070010.
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.
918 x 997 x 493 x 690 x 915 = 284875397115300
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
997 : 1, 997
493 : 1, 17, 29, 493
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,997,493,690,915, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
997:997
493:17x 29
690:2x 3x 5x 23
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 17 = 1530
Therefore, the value for common factors is 1530.
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 = 284875397115300/(1x1530)
LCM = 284875397115300/1530
LCM = 186193070010
Thus, we can understand that the LCM of 918,997,493,690,915 is 186193070010.
