The LCM of 840,499,988,494 is 103532520.
Find LCM of 840,499,988,494 with Prime Factorization
2 | 840, 499, 988, 494 |
2 | 420, 499, 494, 247 |
13 | 210, 499, 247, 247 |
19 | 210, 499, 19, 19 |
210, 499, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 210 x 499 x 1 x 1 = 103532520
Therefore, the lowest common multiple of 840,499,988,494 is 103532520.
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.
840 x 499 x 988 x 494 = 204580259520
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
499 : 1, 499
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,499,988,494, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
499:499
988:2x 2x 13x 19
494:2x 13x 19
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 = 204580259520/(1x1976)
LCM = 204580259520/1976
LCM = 103532520
Thus, we can understand that the LCM of 840,499,988,494 is 103532520.
