Given numbers are 603,678,397,397

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

The LCM of 603,678,397,397 is 54102366.

Find LCM of 603,678,397,397 with Prime Factorization

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

3 x 397 x 201 x 226 x 1 x 1 = 54102366

Therefore, the lowest common multiple of 603,678,397,397 is 54102366.

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.

603 x 678 x 397 x 397 = 64435917906

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.

603 : 1, 3, 9, 67, 201, 603

678 : 1, 2, 3, 6, 113, 226, 339, 678

397 : 1, 397

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 603,678,397,397, is 1.

Now, the common factors can be found like this.

603:3x 3x 67

678:2x 3x 113

397:397

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.

3x 397 = 1191

Therefore, the value for common factors is 1191.

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 = 64435917906/(1x1191)

LCM = 64435917906/1191

LCM = 54102366

Thus, we can understand that the LCM of 603,678,397,397 is 54102366.
