Calculate the LCM of 845,128,821,351

Given numbers are 845,128,821,351

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

The LCM of 845,128,821,351 is 2397582720.

Find LCM of 845,128,821,351 with Prime Factorization


13 845, 128, 821, 351
65, 128, 821, 27

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

13 x 65 x 128 x 821 x 27 = 2397582720

Therefore, the lowest common multiple of 845,128,821,351 is 2397582720.

LCM Formula to Find Lowest Common Multiple of 845,128,821,351

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.

845 x 128 x 821 x 351 = 31168575360

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.

845 : 1, 5, 13, 65, 169, 845

128 : 1, 2, 4, 8, 16, 32, 64, 128

821 : 1, 821

351 : 1, 3, 9, 13, 27, 39, 117, 351

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,128,821,351, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

128:2x 2x 2x 2x 2x 2x 2

821:821

351:3x 3x 3x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 31168575360/(1x13)

LCM = 31168575360/13

LCM = 2397582720

Thus, we can understand that the LCM of 845,128,821,351 is 2397582720.
