Calculate the LCM of 909,458,707,728

Given numbers are 909,458,707,728

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

The LCM of 909,458,707,728 is 151541208.

Find LCM of 909,458,707,728 with Prime Factorization


2 909, 458, 707, 728
7 909, 229, 707, 364
101 909, 229, 101, 52
9, 229, 1, 52

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

2 x 7 x 101 x 9 x 229 x 1 x 52 = 151541208

Therefore, the lowest common multiple of 909,458,707,728 is 151541208.

LCM Formula to Find Lowest Common Multiple of 909,458,707,728

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.

909 x 458 x 707 x 728 = 214279268112

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.

909 : 1, 3, 9, 101, 303, 909

458 : 1, 2, 229, 458

707 : 1, 7, 101, 707

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,458,707,728, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

458:2x 229

707:7x 101

728:2x 2x 2x 7x 13

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

2x 7x 101 = 1414

Therefore, the value for common factors is 1414.

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 = 214279268112/(1x1414)

LCM = 214279268112/1414

LCM = 151541208

Thus, we can understand that the LCM of 909,458,707,728 is 151541208.
