Given numbers are 781,373,407,121

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

The LCM of 781,373,407,121 is 118564391.

Find LCM of 781,373,407,121 with Prime Factorization

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

11 x 71 x 373 x 37 x 11 = 118564391

Therefore, the lowest common multiple of 781,373,407,121 is 118564391.

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.

781 x 373 x 407 x 121 = 14346291311

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.

781 : 1, 11, 71, 781

373 : 1, 373

407 : 1, 11, 37, 407

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,373,407,121, is 1.

Now, the common factors can be found like this.

781:11x 71

373:373

407:11x 37

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 11 = 121

Therefore, the value for common factors is 121.

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 = 14346291311/(1x121)

LCM = 14346291311/121

LCM = 118564391

Thus, we can understand that the LCM of 781,373,407,121 is 118564391.
