Calculate the LCM of 821,558,445,664,544

Given numbers are 821,558,445,664,544

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

The LCM of 821,558,445,664,544 is 4602400025760.

Find LCM of 821,558,445,664,544 with Prime Factorization


2 821, 558, 445, 664, 544
2 821, 279, 445, 332, 272
2 821, 279, 445, 166, 136
821, 279, 445, 83, 68

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

2 x 2 x 2 x 821 x 279 x 445 x 83 x 68 = 4602400025760

Therefore, the lowest common multiple of 821,558,445,664,544 is 4602400025760.

LCM Formula to Find Lowest Common Multiple of 821,558,445,664,544

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.

821 x 558 x 445 x 664 x 544 = 73638400412160

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.

821 : 1, 821

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

445 : 1, 5, 89, 445

664 : 1, 2, 4, 8, 83, 166, 332, 664

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,558,445,664,544, is 1.

Now, the common factors can be found like this.

821:821

558:2x 3x 3x 31

445:5x 89

664:2x 2x 2x 83

544:2x 2x 2x 2x 2x 17

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

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 73638400412160/(1x16)

LCM = 73638400412160/16

LCM = 4602400025760

Thus, we can understand that the LCM of 821,558,445,664,544 is 4602400025760.
