Calculate the LCM of 162,939,787,447,640

Given numbers are 162,939,787,447,640

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

The LCM of 162,939,787,447,640 is 1902700056960.

Find LCM of 162,939,787,447,640 with Prime Factorization


2 162, 939, 787, 447, 640
3 81, 939, 787, 447, 320
27, 313, 787, 149, 320

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

2 x 3 x 27 x 313 x 787 x 149 x 320 = 1902700056960

Therefore, the lowest common multiple of 162,939,787,447,640 is 1902700056960.

LCM Formula to Find Lowest Common Multiple of 162,939,787,447,640

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.

162 x 939 x 787 x 447 x 640 = 34248601025280

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.

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

939 : 1, 3, 313, 939

787 : 1, 787

447 : 1, 3, 149, 447

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,939,787,447,640, is 1.

Now, the common factors can be found like this.

162:2x 3x 3x 3x 3

939:3x 313

787:787

447:3x 149

640:2x 2x 2x 2x 2x 2x 2x 5

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 34248601025280/(1x18)

LCM = 34248601025280/18

LCM = 1902700056960

Thus, we can understand that the LCM of 162,939,787,447,640 is 1902700056960.
