Given numbers are 392,562,791,641

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

The LCM of 392,562,791,641 is 7978639816.

Find LCM of 392,562,791,641 with Prime Factorization

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

2 x 7 x 28 x 281 x 113 x 641 = 7978639816

Therefore, the lowest common multiple of 392,562,791,641 is 7978639816.

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.

392 x 562 x 791 x 641 = 111700957424

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

562 : 1, 2, 281, 562

791 : 1, 7, 113, 791

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,562,791,641, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

562:2x 281

791:7x 113

641:641

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 111700957424/(1x14)

LCM = 111700957424/14

LCM = 7978639816

Thus, we can understand that the LCM of 392,562,791,641 is 7978639816.
