Given numbers are 821,654,146,853,857

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

The LCM of 821,654,146,853,857 is 28653232161822.

Find LCM of 821,654,146,853,857 with Prime Factorization

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

2 x 821 x 327 x 73 x 853 x 857 = 28653232161822

Therefore, the lowest common multiple of 821,654,146,853,857 is 28653232161822.

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.

821 x 654 x 146 x 853 x 857 = 57306464323644

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.

821 : 1, 821

654 : 1, 2, 3, 6, 109, 218, 327, 654

146 : 1, 2, 73, 146

853 : 1, 853

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,654,146,853,857, is 1.

Now, the common factors can be found like this.

821:821

654:2x 3x 109

146:2x 73

853:853

857:857

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

2 = 2

Therefore, the value for common factors is 2.

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 = 57306464323644/(1x2)

LCM = 57306464323644/2

LCM = 28653232161822

Thus, we can understand that the LCM of 821,654,146,853,857 is 28653232161822.
