Given numbers are 518,637,790,393,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,637,790,393,838 is 3066018853170.
Find LCM of 518,637,790,393,838 with Prime Factorization
2 | 518, 637, 790, 393, 838 |
7 | 259, 637, 395, 393, 419 |
37, 91, 395, 393, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 37 x 91 x 395 x 393 x 419 = 3066018853170
Therefore, the lowest common multiple of 518,637,790,393,838 is 3066018853170.
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.
518 x 637 x 790 x 393 x 838 = 85848527888760
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
637 : 1, 7, 13, 49, 91, 637
790 : 1, 2, 5, 10, 79, 158, 395, 790
393 : 1, 3, 131, 393
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,637,790,393,838, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
637:7x 7x 13
790:2x 5x 79
393:3x 131
838:2x 419
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 7 = 28
Therefore, the value for common factors is 28.
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 = 85848527888760/(1x28)
LCM = 85848527888760/28
LCM = 3066018853170
Thus, we can understand that the LCM of 518,637,790,393,838 is 3066018853170.
