Given numbers are 421,208,994,776

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

The LCM of 421,208,994,776 is 4221565712.

Find LCM of 421,208,994,776 with Prime Factorization

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

2 x 2 x 2 x 421 x 26 x 497 x 97 = 4221565712

Therefore, the lowest common multiple of 421,208,994,776 is 4221565712.

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.

421 x 208 x 994 x 776 = 67545051392

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.

421 : 1, 421

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

994 : 1, 2, 7, 14, 71, 142, 497, 994

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,208,994,776, is 1.

Now, the common factors can be found like this.

421:421

208:2x 2x 2x 2x 13

994:2x 7x 71

776:2x 2x 2x 97

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 = 67545051392/(1x16)

LCM = 67545051392/16

LCM = 4221565712

Thus, we can understand that the LCM of 421,208,994,776 is 4221565712.
