Given numbers are 355,163,227,978

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

The LCM of 355,163,227,978 is 78812130.

Find LCM of 355,163,227,978 with Prime Factorization

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

163 x 355 x 1 x 227 x 6 = 78812130

Therefore, the lowest common multiple of 355,163,227,978 is 78812130.

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.

355 x 163 x 227 x 978 = 12846377190

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.

355 : 1, 5, 71, 355

163 : 1, 163

227 : 1, 227

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 355,163,227,978, is 1.

Now, the common factors can be found like this.

355:5x 71

163:163

227:227

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.

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 = 12846377190/(1x163)

LCM = 12846377190/163

LCM = 78812130

Thus, we can understand that the LCM of 355,163,227,978 is 78812130.
