Given numbers are 226,910,644,987,121

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

The LCM of 226,910,644,987,121 is 80701600980.

Find LCM of 226,910,644,987,121 with Prime Factorization

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

2 x 7 x 113 x 65 x 46 x 141 x 121 = 80701600980

Therefore, the lowest common multiple of 226,910,644,987,121 is 80701600980.

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.

226 x 910 x 644 x 987 x 121 = 15817513792080

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.

226 : 1, 2, 113, 226

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

987 : 1, 3, 7, 21, 47, 141, 329, 987

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 226,910,644,987,121, is 1.

Now, the common factors can be found like this.

226:2x 113

910:2x 5x 7x 13

644:2x 2x 7x 23

987:3x 7x 47

121:11x 11

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

2x 2x 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 15817513792080/(1x196)

LCM = 15817513792080/196

LCM = 80701600980

Thus, we can understand that the LCM of 226,910,644,987,121 is 80701600980.
