Given numbers are 635,978,821,163

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

The LCM of 635,978,821,163 is 509865630.

Find LCM of 635,978,821,163 with Prime Factorization

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

163 x 635 x 6 x 821 x 1 = 509865630

Therefore, the lowest common multiple of 635,978,821,163 is 509865630.

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.

635 x 978 x 821 x 163 = 83108097690

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.

635 : 1, 5, 127, 635

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

821 : 1, 821

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,978,821,163, is 1.

Now, the common factors can be found like this.

635:5x 127

978:2x 3x 163

821:821

163:163

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 = 83108097690/(1x163)

LCM = 83108097690/163

LCM = 509865630

Thus, we can understand that the LCM of 635,978,821,163 is 509865630.
