Given numbers are 631,387,317,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,387,317,817 is 1470798531.
Find LCM of 631,387,317,817 with Prime Factorization
43 | 631, 387, 317, 817 |
631, 9, 317, 19 |
Multiply the prime numbers at the bottom and the left side.
43 x 631 x 9 x 317 x 19 = 1470798531
Therefore, the lowest common multiple of 631,387,317,817 is 1470798531.
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.
631 x 387 x 317 x 817 = 63244336833
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.
631 : 1, 631
387 : 1, 3, 9, 43, 129, 387
317 : 1, 317
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,387,317,817, is 1.
Now, the common factors can be found like this.
631:631
387:3x 3x 43
317:317
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 63244336833/(1x43)
LCM = 63244336833/43
LCM = 1470798531
Thus, we can understand that the LCM of 631,387,317,817 is 1470798531.
