Given numbers are 543,518,620,454

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

The LCM of 543,518,620,454 is 19793251380.

Find LCM of 543,518,620,454 with Prime Factorization

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

2 x 543 x 259 x 310 x 227 = 19793251380

Therefore, the lowest common multiple of 543,518,620,454 is 19793251380.

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.

543 x 518 x 620 x 454 = 79173005520

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.

543 : 1, 3, 181, 543

518 : 1, 2, 7, 14, 37, 74, 259, 518

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,518,620,454, is 1.

Now, the common factors can be found like this.

543:3x 181

518:2x 7x 37

620:2x 2x 5x 31

454:2x 227

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 79173005520/(1x4)

LCM = 79173005520/4

LCM = 19793251380

Thus, we can understand that the LCM of 543,518,620,454 is 19793251380.
