Given numbers are 420,939,643,884,336

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

The LCM of 420,939,643,884,336 is 74723441520.

Find LCM of 420,939,643,884,336 with Prime Factorization

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

2 x 2 x 3 x 7 x 5 x 313 x 643 x 221 x 4 = 74723441520

Therefore, the lowest common multiple of 420,939,643,884,336 is 74723441520.

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 939 x 643 x 884 x 336 = 75321229052160

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

939 : 1, 3, 313, 939

643 : 1, 643

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,939,643,884,336, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

939:3x 313

643:643

884:2x 2x 13x 17

336:2x 2x 2x 2x 3x 7

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 2x 3x 3x 7 = 1008

Therefore, the value for common factors is 1008.

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 = 75321229052160/(1x1008)

LCM = 75321229052160/1008

LCM = 74723441520

Thus, we can understand that the LCM of 420,939,643,884,336 is 74723441520.
