The LCM of 598,494,938,690 is 79931670.
Find LCM of 598,494,938,690 with Prime Factorization
| 2 | 598, 494, 938, 690 |
| 13 | 299, 247, 469, 345 |
| 23 | 23, 19, 469, 345 |
| 1, 19, 469, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 23 x 1 x 19 x 469 x 15 = 79931670
Therefore, the lowest common multiple of 598,494,938,690 is 79931670.
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.
598 x 494 x 938 x 690 = 191196554640
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.
598 : 1, 2, 13, 23, 26, 46, 299, 598
494 : 1, 2, 13, 19, 26, 38, 247, 494
938 : 1, 2, 7, 14, 67, 134, 469, 938
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,494,938,690, is 2.
Now, the common factors can be found like this.
598:2x 13x 23
494:2x 13x 19
938:2x 7x 67
690:2x 3x 5x 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 13x 23 = 1196
Therefore, the value for common factors is 1196.
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 = 191196554640/(2x1196)
LCM = 191196554640/2392
LCM = 79931670
Thus, we can understand that the LCM of 598,494,938,690 is 79931670.
