Given numbers are 124,128,160,427

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

The LCM of 124,128,160,427 is 8471680.

Find LCM of 124,128,160,427 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 31 x 4 x 5 x 427 = 8471680

Therefore, the lowest common multiple of 124,128,160,427 is 8471680.

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.

124 x 128 x 160 x 427 = 1084375040

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.

124 : 1, 2, 4, 31, 62, 124

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

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,128,160,427, is 1.

Now, the common factors can be found like this.

124:2x 2x 31

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

160:2x 2x 2x 2x 2x 5

427:7x 61

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 2 = 128

Therefore, the value for common factors is 128.

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 = 1084375040/(1x128)

LCM = 1084375040/128

LCM = 8471680

Thus, we can understand that the LCM of 124,128,160,427 is 8471680.
