Given numbers are 820,423,778,201

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

The LCM of 820,423,778,201 is 9040212180.

Find LCM of 820,423,778,201 with Prime Factorization

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

2 x 3 x 410 x 141 x 389 x 67 = 9040212180

Therefore, the lowest common multiple of 820,423,778,201 is 9040212180.

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.

820 x 423 x 778 x 201 = 54241273080

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

423 : 1, 3, 9, 47, 141, 423

778 : 1, 2, 389, 778

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,423,778,201, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

423:3x 3x 47

778:2x 389

201:3x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 54241273080/(1x6)

LCM = 54241273080/6

LCM = 9040212180

Thus, we can understand that the LCM of 820,423,778,201 is 9040212180.
