Given numbers are 685,722,978,358

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

The LCM of 685,722,978,358 is 43290206670.

Find LCM of 685,722,978,358 with Prime Factorization

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

2 x 685 x 361 x 489 x 179 = 43290206670

Therefore, the lowest common multiple of 685,722,978,358 is 43290206670.

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.

685 x 722 x 978 x 358 = 173160826680

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.

685 : 1, 5, 137, 685

722 : 1, 2, 19, 38, 361, 722

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

358 : 1, 2, 179, 358

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,722,978,358, is 1.

Now, the common factors can be found like this.

685:5x 137

722:2x 19x 19

978:2x 3x 163

358:2x 179

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 173160826680/(1x4)

LCM = 173160826680/4

LCM = 43290206670

Thus, we can understand that the LCM of 685,722,978,358 is 43290206670.
