Given numbers are 972,680,283,478,865

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

The LCM of 972,680,283,478,865 is 1933506453240.

Find LCM of 972,680,283,478,865 with Prime Factorization

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

2 x 2 x 5 x 243 x 34 x 283 x 239 x 173 = 1933506453240

Therefore, the lowest common multiple of 972,680,283,478,865 is 1933506453240.

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.

972 x 680 x 283 x 478 x 865 = 77340258129600

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.

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

283 : 1, 283

478 : 1, 2, 239, 478

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,680,283,478,865, is 1.

Now, the common factors can be found like this.

972:2x 2x 3x 3x 3x 3x 3

680:2x 2x 2x 5x 17

283:283

478:2x 239

865:5x 173

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 5 = 40

Therefore, the value for common factors is 40.

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 = 77340258129600/(1x40)

LCM = 77340258129600/40

LCM = 1933506453240

Thus, we can understand that the LCM of 972,680,283,478,865 is 1933506453240.
