Given numbers are 840,845,121,955

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

The LCM of 840,845,121,955 is 3280837560.

Find LCM of 840,845,121,955 with Prime Factorization

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

5 x 168 x 169 x 121 x 191 = 3280837560

Therefore, the lowest common multiple of 840,845,121,955 is 3280837560.

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.

840 x 845 x 121 x 955 = 82020939000

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

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

121 : 1, 11, 121

955 : 1, 5, 191, 955

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,845,121,955, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

845:5x 13x 13

121:11x 11

955:5x 191

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 82020939000/(1x25)

LCM = 82020939000/25

LCM = 3280837560

Thus, we can understand that the LCM of 840,845,121,955 is 3280837560.
