Given numbers are 670,378,197,811

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

The LCM of 670,378,197,811 is 20231295210.

Find LCM of 670,378,197,811 with Prime Factorization

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

2 x 335 x 189 x 197 x 811 = 20231295210

Therefore, the lowest common multiple of 670,378,197,811 is 20231295210.

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.

670 x 378 x 197 x 811 = 40462590420

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

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

197 : 1, 197

811 : 1, 811

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,378,197,811, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

378:2x 3x 3x 3x 7

197:197

811:811

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

2 = 2

Therefore, the value for common factors is 2.

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 = 40462590420/(1x2)

LCM = 40462590420/2

LCM = 20231295210

Thus, we can understand that the LCM of 670,378,197,811 is 20231295210.
