Given numbers are 677,921,847,434,621

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

The LCM of 677,921,847,434,621 is 6777877949766.

Find LCM of 677,921,847,434,621 with Prime Factorization

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

3 x 7 x 677 x 307 x 121 x 62 x 207 = 6777877949766

Therefore, the lowest common multiple of 677,921,847,434,621 is 6777877949766.

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.

677 x 921 x 847 x 434 x 621 = 142335436945086

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.

677 : 1, 677

921 : 1, 3, 307, 921

847 : 1, 7, 11, 77, 121, 847

434 : 1, 2, 7, 14, 31, 62, 217, 434

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,921,847,434,621, is 1.

Now, the common factors can be found like this.

677:677

921:3x 307

847:7x 11x 11

434:2x 7x 31

621:3x 3x 3x 23

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 142335436945086/(1x21)

LCM = 142335436945086/21

LCM = 6777877949766

Thus, we can understand that the LCM of 677,921,847,434,621 is 6777877949766.
