The LCM of 989,497,308,687 is 14858059524.

Find LCM of 989,497,308,687 with Prime Factorization


7 989, 497, 308, 687
989, 71, 44, 687

Multiply the prime numbers at the bottom and the left side.

7 x 989 x 71 x 44 x 687 = 14858059524

Therefore, the lowest common multiple of 989,497,308,687 is 14858059524.

LCM Formula to Find Lowest Common Multiple of 989,497,308,687

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.

989 x 497 x 308 x 687 = 104006416668

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.

989 : 1, 23, 43, 989

497 : 1, 7, 71, 497

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,497,308,687, is 1.

Now, the common factors can be found like this.

989:23x 43

497:7x 71

308:2x 2x 7x 11

687:3x 229

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7 = 7

Therefore, the value for common factors is 7.

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 = 104006416668/(1x7)

LCM = 104006416668/7

LCM = 14858059524

Thus, we can understand that the LCM of 989,497,308,687 is 14858059524.
