Given numbers are 864,571,421,986,641

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

The LCM of 864,571,421,986,641 is 65635212455712.

Find LCM of 864,571,421,986,641 with Prime Factorization

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

2 x 432 x 571 x 421 x 493 x 641 = 65635212455712

Therefore, the lowest common multiple of 864,571,421,986,641 is 65635212455712.

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.

864 x 571 x 421 x 986 x 641 = 131270424911424

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.

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

571 : 1, 571

421 : 1, 421

986 : 1, 2, 17, 29, 34, 58, 493, 986

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,571,421,986,641, is 1.

Now, the common factors can be found like this.

864:2x 2x 2x 2x 2x 3x 3x 3

571:571

421:421

986:2x 17x 29

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.

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 = 131270424911424/(1x2)

LCM = 131270424911424/2

LCM = 65635212455712

Thus, we can understand that the LCM of 864,571,421,986,641 is 65635212455712.
