Find LCM of 605,794,490,988,397 with Prime Factorization
2 | 605, 794, 490, 988, 397 |
5 | 605, 397, 245, 494, 397 |
397 | 121, 397, 49, 494, 397 |
121, 1, 49, 494, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 397 x 121 x 1 x 49 x 494 x 1 = 11627836220
Therefore, the lowest common multiple of 605,794,490,988,397 is 11627836220.
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.
605 x 794 x 490 x 988 x 397 = 92325019586800
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.
605 : 1, 5, 11, 55, 121, 605
794 : 1, 2, 397, 794
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,794,490,988,397, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
794:2x 397
490:2x 5x 7x 7
988:2x 2x 13x 19
397:397
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 5x 397 = 7940
Therefore, the value for common factors is 7940.
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 = 92325019586800/(1x7940)
LCM = 92325019586800/7940
LCM = 11627836220
Thus, we can understand that the LCM of 605,794,490,988,397 is 11627836220.
