Calculate the LCM of 555,440,861,938

Given numbers are 555,440,861,938

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

The LCM of 555,440,861,938 is 939144360.

Find LCM of 555,440,861,938 with Prime Factorization


2 555, 440, 861, 938
3 555, 220, 861, 469
5 185, 220, 287, 469
7 37, 44, 287, 469
37, 44, 41, 67

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

2 x 3 x 5 x 7 x 37 x 44 x 41 x 67 = 939144360

Therefore, the lowest common multiple of 555,440,861,938 is 939144360.

LCM Formula to Find Lowest Common Multiple of 555,440,861,938

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.

555 x 440 x 861 x 938 = 197220315600

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.

555 : 1, 3, 5, 15, 37, 111, 185, 555

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

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

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,440,861,938, is 1.

Now, the common factors can be found like this.

555:3x 5x 37

440:2x 2x 2x 5x 11

861:3x 7x 41

938:2x 7x 67

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 5x 7 = 210

Therefore, the value for common factors is 210.

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 = 197220315600/(1x210)

LCM = 197220315600/210

LCM = 939144360

Thus, we can understand that the LCM of 555,440,861,938 is 939144360.
