Given numbers are 199,313,440,497,978

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

The LCM of 199,313,440,497,978 is 6660630447240.

Find LCM of 199,313,440,497,978 with Prime Factorization

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

2 x 199 x 313 x 220 x 497 x 489 = 6660630447240

Therefore, the lowest common multiple of 199,313,440,497,978 is 6660630447240.

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.

199 x 313 x 440 x 497 x 978 = 13321260894480

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.

199 : 1, 199

313 : 1, 313

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

497 : 1, 7, 71, 497

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 199,313,440,497,978, is 1.

Now, the common factors can be found like this.

199:199

313:313

440:2x 2x 2x 5x 11

497:7x 71

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 13321260894480/(1x2)

LCM = 13321260894480/2

LCM = 6660630447240

Thus, we can understand that the LCM of 199,313,440,497,978 is 6660630447240.
