Given numbers are 920,128,880,923

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

The LCM of 920,128,880,923 is 149452160.

Find LCM of 920,128,880,923 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 23 x 8 x 11 x 923 = 149452160

Therefore, the lowest common multiple of 920,128,880,923 is 149452160.

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.

920 x 128 x 880 x 923 = 95649382400

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

128 : 1, 2, 4, 8, 16, 32, 64, 128

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,128,880,923, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

128:2x 2x 2x 2x 2x 2x 2

880:2x 2x 2x 2x 5x 11

923:13x 71

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

2x 2x 2x 2x 2x 2x 2x 5 = 640

Therefore, the value for common factors is 640.

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 = 95649382400/(1x640)

LCM = 95649382400/640

LCM = 149452160

Thus, we can understand that the LCM of 920,128,880,923 is 149452160.
