Given numbers are 644,476,707,728,994

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

The LCM of 644,476,707,728,994 is 2041210808.

Find LCM of 644,476,707,728,994 with Prime Factorization

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

2 x 2 x 7 x 23 x 17 x 101 x 26 x 71 = 2041210808

Therefore, the lowest common multiple of 644,476,707,728,994 is 2041210808.

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.

644 x 476 x 707 x 728 x 994 = 156830308800256

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

707 : 1, 7, 101, 707

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

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

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,476,707,728,994, is 7.

Now, the common factors can be found like this.

644:2x 2x 7x 23

476:2x 2x 7x 17

707:7x 101

728:2x 2x 2x 7x 13

994:2x 7x 71

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 2x 7x 7x 7 = 10976

Therefore, the value for common factors is 10976.

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 = 156830308800256/(7x10976)

LCM = 156830308800256/76832

LCM = 2041210808

Thus, we can understand that the LCM of 644,476,707,728,994 is 2041210808.
