Given numbers are 548,742,421,387

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

The LCM of 548,742,421,387 is 33124362516.

Find LCM of 548,742,421,387 with Prime Factorization

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

2 x 274 x 371 x 421 x 387 = 33124362516

Therefore, the lowest common multiple of 548,742,421,387 is 33124362516.

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.

548 x 742 x 421 x 387 = 66248725032

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.

548 : 1, 2, 4, 137, 274, 548

742 : 1, 2, 7, 14, 53, 106, 371, 742

421 : 1, 421

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,742,421,387, is 1.

Now, the common factors can be found like this.

548:2x 2x 137

742:2x 7x 53

421:421

387:3x 3x 43

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 = 66248725032/(1x2)

LCM = 66248725032/2

LCM = 33124362516

Thus, we can understand that the LCM of 548,742,421,387 is 33124362516.
