Given numbers are 197,778,378,220,402

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

The LCM of 197,778,378,220,402 is 213488809380.

Find LCM of 197,778,378,220,402 with Prime Factorization

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

2 x 3 x 197 x 389 x 63 x 110 x 67 = 213488809380

Therefore, the lowest common multiple of 197,778,378,220,402 is 213488809380.

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.

197 x 778 x 378 x 220 x 402 = 5123731425120

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.

197 : 1, 197

778 : 1, 2, 389, 778

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,778,378,220,402, is 1.

Now, the common factors can be found like this.

197:197

778:2x 389

378:2x 3x 3x 3x 7

220:2x 2x 5x 11

402:2x 3x 67

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 5123731425120/(1x24)

LCM = 5123731425120/24

LCM = 213488809380

Thus, we can understand that the LCM of 197,778,378,220,402 is 213488809380.
