Find LCM of 331,486,945,973 with Prime Factorization


3 331, 486, 945, 973
3 331, 162, 315, 973
3 331, 54, 105, 973
7 331, 18, 35, 973
331, 18, 5, 139

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

3 x 3 x 3 x 7 x 331 x 18 x 5 x 139 = 782613090

Therefore, the lowest common multiple of 331,486,945,973 is 782613090.

LCM Formula to Find Lowest Common Multiple of 331,486,945,973

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.

331 x 486 x 945 x 973 = 147913874010

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.

331 : 1, 331

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,486,945,973, is 1.

Now, the common factors can be found like this.

331:331

486:2x 3x 3x 3x 3x 3

945:3x 3x 3x 5x 7

973:7x 139

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

3x 3x 3x 7 = 189

Therefore, the value for common factors is 189.

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 = 147913874010/(1x189)

LCM = 147913874010/189

LCM = 782613090

Thus, we can understand that the LCM of 331,486,945,973 is 782613090.
