Given numbers are 163,243,420,859,978

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

The LCM of 163,243,420,859,978 is 4763378340.

Find LCM of 163,243,420,859,978 with Prime Factorization

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

2 x 3 x 163 x 1 x 81 x 70 x 859 x 1 = 4763378340

Therefore, the lowest common multiple of 163,243,420,859,978 is 4763378340.

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.

163 x 243 x 420 x 859 x 978 = 13975752049560

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.

163 : 1, 163

243 : 1, 3, 9, 27, 81, 243

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

859 : 1, 859

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 163,243,420,859,978, is 1.

Now, the common factors can be found like this.

163:163

243:3x 3x 3x 3x 3

420:2x 2x 3x 5x 7

859:859

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.

2x 3x 3x 163 = 2934

Therefore, the value for common factors is 2934.

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 = 13975752049560/(1x2934)

LCM = 13975752049560/2934

LCM = 4763378340

Thus, we can understand that the LCM of 163,243,420,859,978 is 4763378340.
