Given numbers are 555,642,234,674,978

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

The LCM of 555,642,234,674,978 is 254442039930.

Find LCM of 555,642,234,674,978 with Prime Factorization

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

2 x 3 x 185 x 107 x 39 x 337 x 163 = 254442039930

Therefore, the lowest common multiple of 555,642,234,674,978 is 254442039930.

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 642 x 234 x 674 x 978 = 54959480624880

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

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

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

674 : 1, 2, 337, 674

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,642,234,674,978, is 1.

Now, the common factors can be found like this.

555:3x 5x 37

642:2x 3x 107

234:2x 3x 3x 13

674:2x 337

978:2x 3x 163

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

2x 2x 2x 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 54959480624880/(1x216)

LCM = 54959480624880/216

LCM = 254442039930

Thus, we can understand that the LCM of 555,642,234,674,978 is 254442039930.
