Given numbers are 420,397,582,541

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

The LCM of 420,397,582,541 is 8750014980.

Find LCM of 420,397,582,541 with Prime Factorization

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

2 x 3 x 70 x 397 x 97 x 541 = 8750014980

Therefore, the lowest common multiple of 420,397,582,541 is 8750014980.

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.

420 x 397 x 582 x 541 = 52500089880

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

397 : 1, 397

582 : 1, 2, 3, 6, 97, 194, 291, 582

541 : 1, 541

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,397,582,541, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

397:397

582:2x 3x 97

541:541

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 52500089880/(1x6)

LCM = 52500089880/6

LCM = 8750014980

Thus, we can understand that the LCM of 420,397,582,541 is 8750014980.
