Given numbers are 660,897,578,190,981

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

The LCM of 660,897,578,190,981 is 354335218380.

Find LCM of 660,897,578,190,981 with Prime Factorization

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

2 x 3 x 5 x 22 x 299 x 289 x 19 x 327 = 354335218380

Therefore, the lowest common multiple of 660,897,578,190,981 is 354335218380.

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.

660 x 897 x 578 x 190 x 981 = 63780339308400

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

897 : 1, 3, 13, 23, 39, 69, 299, 897

578 : 1, 2, 17, 34, 289, 578

190 : 1, 2, 5, 10, 19, 38, 95, 190

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,897,578,190,981, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

897:3x 13x 23

578:2x 17x 17

190:2x 5x 19

981:3x 3x 109

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 63780339308400/(1x180)

LCM = 63780339308400/180

LCM = 354335218380

Thus, we can understand that the LCM of 660,897,578,190,981 is 354335218380.
