Given numbers are 203,203,640,403

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

The LCM of 203,203,640,403 is 52357760.

Find LCM of 203,203,640,403 with Prime Factorization

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

7 x 29 x 1 x 1 x 640 x 403 = 52357760

Therefore, the lowest common multiple of 203,203,640,403 is 52357760.

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.

203 x 203 x 640 x 403 = 10628625280

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.

203 : 1, 7, 29, 203

203 : 1, 7, 29, 203

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

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,203,640,403, is 1.

Now, the common factors can be found like this.

203:7x 29

203:7x 29

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

403:13x 31

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

7x 29 = 203

Therefore, the value for common factors is 203.

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 = 10628625280/(1x203)

LCM = 10628625280/203

LCM = 52357760

Thus, we can understand that the LCM of 203,203,640,403 is 52357760.
