Given numbers are 516,507,638,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,507,638,989 is 639815748.
Find LCM of 516,507,638,989 with Prime Factorization
2 | 516, 507, 638, 989 |
3 | 258, 507, 319, 989 |
43 | 86, 169, 319, 989 |
2, 169, 319, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 2 x 169 x 319 x 23 = 639815748
Therefore, the lowest common multiple of 516,507,638,989 is 639815748.
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.
516 x 507 x 638 x 989 = 165072462984
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
507 : 1, 3, 13, 39, 169, 507
638 : 1, 2, 11, 22, 29, 58, 319, 638
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,507,638,989, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
507:3x 13x 13
638:2x 11x 29
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 43 = 258
Therefore, the value for common factors is 258.
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 = 165072462984/(1x258)
LCM = 165072462984/258
LCM = 639815748
Thus, we can understand that the LCM of 516,507,638,989 is 639815748.
