Given numbers are 390,960,657,203

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

The LCM of 390,960,657,203 is 554823360.

Find LCM of 390,960,657,203 with Prime Factorization

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

2 x 3 x 5 x 13 x 32 x 219 x 203 = 554823360

Therefore, the lowest common multiple of 390,960,657,203 is 554823360.

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.

390 x 960 x 657 x 203 = 49934102400

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

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

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,960,657,203, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

960:2x 2x 2x 2x 2x 2x 3x 5

657:3x 3x 73

203:7x 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 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 49934102400/(1x90)

LCM = 49934102400/90

LCM = 554823360

Thus, we can understand that the LCM of 390,960,657,203 is 554823360.
