Find LCM of 697,494,663,984 with Prime Factorization
| 2 | 697, 494, 663, 984 |
| 3 | 697, 247, 663, 492 |
| 13 | 697, 247, 221, 164 |
| 17 | 697, 19, 17, 164 |
| 41 | 41, 19, 1, 164 |
| 1, 19, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 41 x 1 x 19 x 1 x 4 = 4131816
Therefore, the lowest common multiple of 697,494,663,984 is 4131816.
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.
697 x 494 x 663 x 984 = 224630308656
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.
697 : 1, 17, 41, 697
494 : 1, 2, 13, 19, 26, 38, 247, 494
663 : 1, 3, 13, 17, 39, 51, 221, 663
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,494,663,984, is 1.
Now, the common factors can be found like this.
697:17x 41
494:2x 13x 19
663:3x 13x 17
984:2x 2x 2x 3x 41
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 13x 17x 41 = 54366
Therefore, the value for common factors is 54366.
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 = 224630308656/(1x54366)
LCM = 224630308656/54366
LCM = 4131816
Thus, we can understand that the LCM of 697,494,663,984 is 4131816.
