Given numbers are 605,163,978,709

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

The LCM of 605,163,978,709 is 419508210.

Find LCM of 605,163,978,709 with Prime Factorization

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

163 x 605 x 1 x 6 x 709 = 419508210

Therefore, the lowest common multiple of 605,163,978,709 is 419508210.

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.

605 x 163 x 978 x 709 = 68379838230

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.

605 : 1, 5, 11, 55, 121, 605

163 : 1, 163

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

709 : 1, 709

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,163,978,709, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

163:163

978:2x 3x 163

709:709

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

163 = 163

Therefore, the value for common factors is 163.

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 = 68379838230/(1x163)

LCM = 68379838230/163

LCM = 419508210

Thus, we can understand that the LCM of 605,163,978,709 is 419508210.
