Given numbers are 921,865,748,121

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

The LCM of 921,865,748,121 is 6554959620.

Find LCM of 921,865,748,121 with Prime Factorization

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

11 x 921 x 865 x 68 x 11 = 6554959620

Therefore, the lowest common multiple of 921,865,748,121 is 6554959620.

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.

921 x 865 x 748 x 121 = 72104555820

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.

921 : 1, 3, 307, 921

865 : 1, 5, 173, 865

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,865,748,121, is 1.

Now, the common factors can be found like this.

921:3x 307

865:5x 173

748:2x 2x 11x 17

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 72104555820/(1x11)

LCM = 72104555820/11

LCM = 6554959620

Thus, we can understand that the LCM of 921,865,748,121 is 6554959620.
