Given numbers are 203,142,766,638

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

The LCM of 203,142,766,638 is 121443938.

Find LCM of 203,142,766,638 with Prime Factorization

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

2 x 29 x 7 x 71 x 383 x 11 = 121443938

Therefore, the lowest common multiple of 203,142,766,638 is 121443938.

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 142 x 766 x 638 = 14087496808

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

142 : 1, 2, 71, 142

766 : 1, 2, 383, 766

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,142,766,638, is 1.

Now, the common factors can be found like this.

203:7x 29

142:2x 71

766:2x 383

638:2x 11x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 14087496808/(1x116)

LCM = 14087496808/116

LCM = 121443938

Thus, we can understand that the LCM of 203,142,766,638 is 121443938.
