Calculate the LCM of 407,905,945,682

Given numbers are 407,905,945,682

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

The LCM of 407,905,945,682 is 4316149530.

Find LCM of 407,905,945,682 with Prime Factorization


5 407, 905, 945, 682
11 407, 181, 189, 682
37, 181, 189, 62

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

5 x 11 x 37 x 181 x 189 x 62 = 4316149530

Therefore, the lowest common multiple of 407,905,945,682 is 4316149530.

LCM Formula to Find Lowest Common Multiple of 407,905,945,682

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.

407 x 905 x 945 x 682 = 237388224150

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.

407 : 1, 11, 37, 407

905 : 1, 5, 181, 905

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

682 : 1, 2, 11, 22, 31, 62, 341, 682

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,905,945,682, is 1.

Now, the common factors can be found like this.

407:11x 37

905:5x 181

945:3x 3x 3x 5x 7

682:2x 11x 31

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

5x 11 = 55

Therefore, the value for common factors is 55.

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 = 237388224150/(1x55)

LCM = 237388224150/55

LCM = 4316149530

Thus, we can understand that the LCM of 407,905,945,682 is 4316149530.
