Given numbers are 517,393,748,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,393,748,631 is 8718090348.
Find LCM of 517,393,748,631 with Prime Factorization
| 11 | 517, 393, 748, 631 |
| 47, 393, 68, 631 |
Multiply the prime numbers at the bottom and the left side.
11 x 47 x 393 x 68 x 631 = 8718090348
Therefore, the lowest common multiple of 517,393,748,631 is 8718090348.
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.
517 x 393 x 748 x 631 = 95898993828
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.
517 : 1, 11, 47, 517
393 : 1, 3, 131, 393
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,393,748,631, is 1.
Now, the common factors can be found like this.
517:11x 47
393:3x 131
748:2x 2x 11x 17
631:631
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 95898993828/(1x11)
LCM = 95898993828/11
LCM = 8718090348
Thus, we can understand that the LCM of 517,393,748,631 is 8718090348.
