Given numbers are 121,748,143,121

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

The LCM of 121,748,143,121 is 106964.

Find LCM of 121,748,143,121 with Prime Factorization

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

11 x 11 x 1 x 68 x 13 x 1 = 106964

Therefore, the lowest common multiple of 121,748,143,121 is 106964.

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.

121 x 748 x 143 x 121 = 1566059924

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.

121 : 1, 11, 121

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

143 : 1, 11, 13, 143

121 : 1, 11, 121

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,748,143,121, is 11.

Now, the common factors can be found like this.

121:11x 11

748:2x 2x 11x 17

143:11x 13

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.

11x 11x 11 = 1331

Therefore, the value for common factors is 1331.

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 = 1566059924/(11x1331)

LCM = 1566059924/14641

LCM = 106964

Thus, we can understand that the LCM of 121,748,143,121 is 106964.
