Given numbers are 428,611,554,455

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

The LCM of 428,611,554,455 is 2535320060.

Find LCM of 428,611,554,455 with Prime Factorization

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

2 x 13 x 214 x 47 x 277 x 35 = 2535320060

Therefore, the lowest common multiple of 428,611,554,455 is 2535320060.

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.

428 x 611 x 554 x 455 = 65918321560

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.

428 : 1, 2, 4, 107, 214, 428

611 : 1, 13, 47, 611

554 : 1, 2, 277, 554

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,611,554,455, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

611:13x 47

554:2x 277

455:5x 7x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 65918321560/(1x26)

LCM = 65918321560/26

LCM = 2535320060

Thus, we can understand that the LCM of 428,611,554,455 is 2535320060.
