Given numbers are 202,770,320,397

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

The LCM of 202,770,320,397 is 987990080.

Find LCM of 202,770,320,397 with Prime Factorization

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

2 x 5 x 101 x 77 x 32 x 397 = 987990080

Therefore, the lowest common multiple of 202,770,320,397 is 987990080.

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.

202 x 770 x 320 x 397 = 19759801600

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.

202 : 1, 2, 101, 202

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

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

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,770,320,397, is 1.

Now, the common factors can be found like this.

202:2x 101

770:2x 5x 7x 11

320:2x 2x 2x 2x 2x 2x 5

397:397

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 5 = 20

Therefore, the value for common factors is 20.

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 = 19759801600/(1x20)

LCM = 19759801600/20

LCM = 987990080

Thus, we can understand that the LCM of 202,770,320,397 is 987990080.
