Calculate the LCM of 351,989,731,242

Given numbers are 351,989,731,242

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 351,989,731,242 is 1428129846.

Find LCM of 351,989,731,242 with Prime Factorization


43 351, 989, 731, 242
351, 23, 17, 242

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

43 x 351 x 23 x 17 x 242 = 1428129846

Therefore, the lowest common multiple of 351,989,731,242 is 1428129846.

LCM Formula to Find Lowest Common Multiple of 351,989,731,242

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.

351 x 989 x 731 x 242 = 61409583378

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

989 : 1, 23, 43, 989

731 : 1, 17, 43, 731

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,989,731,242, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

989:23x 43

731:17x 43

242:2x 11x 11

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 = 61409583378/(1x43)

LCM = 61409583378/43

LCM = 1428129846

Thus, we can understand that the LCM of 351,989,731,242 is 1428129846.
