Given numbers are 770,727,921,614,646

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

The LCM of 770,727,921,614,646 is 166528008570.

Find LCM of 770,727,921,614,646 with Prime Factorization

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

2 x 307 x 385 x 727 x 3 x 1 x 323 = 166528008570

Therefore, the lowest common multiple of 770,727,921,614,646 is 166528008570.

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.

770 x 727 x 921 x 614 x 646 = 204496394523960

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

727 : 1, 727

921 : 1, 3, 307, 921

614 : 1, 2, 307, 614

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,727,921,614,646, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

727:727

921:3x 307

614:2x 307

646:2x 17x 19

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 307 = 1228

Therefore, the value for common factors is 1228.

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 = 204496394523960/(1x1228)

LCM = 204496394523960/1228

LCM = 166528008570

Thus, we can understand that the LCM of 770,727,921,614,646 is 166528008570.
