Calculate the LCM of 907,861,495,642

Given numbers are 907,861,495,642

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

The LCM of 907,861,495,642 is 27574532370.

Find LCM of 907,861,495,642 with Prime Factorization


3 907, 861, 495, 642
907, 287, 165, 214

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

3 x 907 x 287 x 165 x 214 = 27574532370

Therefore, the lowest common multiple of 907,861,495,642 is 27574532370.

LCM Formula to Find Lowest Common Multiple of 907,861,495,642

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.

907 x 861 x 495 x 642 = 248170791330

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.

907 : 1, 907

861 : 1, 3, 7, 21, 41, 123, 287, 861

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,861,495,642, is 1.

Now, the common factors can be found like this.

907:907

861:3x 7x 41

495:3x 3x 5x 11

642:2x 3x 107

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 248170791330/(1x9)

LCM = 248170791330/9

LCM = 27574532370

Thus, we can understand that the LCM of 907,861,495,642 is 27574532370.
