Given numbers are 635,438,657,993

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

The LCM of 635,438,657,993 is 276183090.

Find LCM of 635,438,657,993 with Prime Factorization

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

3 x 73 x 635 x 2 x 3 x 331 = 276183090

Therefore, the lowest common multiple of 635,438,657,993 is 276183090.

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.

635 x 438 x 657 x 993 = 181452290130

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.

635 : 1, 5, 127, 635

438 : 1, 2, 3, 6, 73, 146, 219, 438

657 : 1, 3, 9, 73, 219, 657

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,438,657,993, is 1.

Now, the common factors can be found like this.

635:5x 127

438:2x 3x 73

657:3x 3x 73

993:3x 331

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

3x 3x 73 = 657

Therefore, the value for common factors is 657.

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 = 181452290130/(1x657)

LCM = 181452290130/657

LCM = 276183090

Thus, we can understand that the LCM of 635,438,657,993 is 276183090.
