Given numbers are 157,407,121,381

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

The LCM of 157,407,121,381 is 267800709.

Find LCM of 157,407,121,381 with Prime Factorization

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

11 x 157 x 37 x 11 x 381 = 267800709

Therefore, the lowest common multiple of 157,407,121,381 is 267800709.

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.

157 x 407 x 121 x 381 = 2945807799

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.

157 : 1, 157

407 : 1, 11, 37, 407

121 : 1, 11, 121

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,407,121,381, is 1.

Now, the common factors can be found like this.

157:157

407:11x 37

121:11x 11

381:3x 127

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 = 2945807799/(1x11)

LCM = 2945807799/11

LCM = 267800709

Thus, we can understand that the LCM of 157,407,121,381 is 267800709.
