Given numbers are 775,672,135,873,421

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

The LCM of 775,672,135,873,421 is 191411186400.

Find LCM of 775,672,135,873,421 with Prime Factorization

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

3 x 3 x 5 x 155 x 224 x 3 x 97 x 421 = 191411186400

Therefore, the lowest common multiple of 775,672,135,873,421 is 191411186400.

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.

775 x 672 x 135 x 873 x 421 = 25840510164000

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.

775 : 1, 5, 25, 31, 155, 775

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

135 : 1, 3, 5, 9, 15, 27, 45, 135

873 : 1, 3, 9, 97, 291, 873

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,672,135,873,421, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

672:2x 2x 2x 2x 2x 3x 7

135:3x 3x 3x 5

873:3x 3x 97

421:421

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

3x 3x 3x 5 = 135

Therefore, the value for common factors is 135.

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 = 25840510164000/(1x135)

LCM = 25840510164000/135

LCM = 191411186400

Thus, we can understand that the LCM of 775,672,135,873,421 is 191411186400.
