Given numbers are 128,322,403,532

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

The LCM of 128,322,403,532 is 157795456.

Find LCM of 128,322,403,532 with Prime Factorization

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

2 x 2 x 7 x 32 x 23 x 403 x 19 = 157795456

Therefore, the lowest common multiple of 128,322,403,532 is 157795456.

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.

128 x 322 x 403 x 532 = 8836545536

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.

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

322 : 1, 2, 7, 14, 23, 46, 161, 322

403 : 1, 13, 31, 403

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,322,403,532, is 1.

Now, the common factors can be found like this.

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

322:2x 7x 23

403:13x 31

532:2x 2x 7x 19

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 7 = 56

Therefore, the value for common factors is 56.

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 = 8836545536/(1x56)

LCM = 8836545536/56

LCM = 157795456

Thus, we can understand that the LCM of 128,322,403,532 is 157795456.
