Given numbers are 149,135,785,640

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

The LCM of 149,135,785,640 is 404231040.

Find LCM of 149,135,785,640 with Prime Factorization

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

5 x 149 x 27 x 157 x 128 = 404231040

Therefore, the lowest common multiple of 149,135,785,640 is 404231040.

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.

149 x 135 x 785 x 640 = 10105776000

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.

149 : 1, 149

135 : 1, 3, 5, 9, 15, 27, 45, 135

785 : 1, 5, 157, 785

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,135,785,640, is 1.

Now, the common factors can be found like this.

149:149

135:3x 3x 3x 5

785:5x 157

640:2x 2x 2x 2x 2x 2x 2x 5

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 10105776000/(1x25)

LCM = 10105776000/25

LCM = 404231040

Thus, we can understand that the LCM of 149,135,785,640 is 404231040.
