Calculate the LCM of 287,321,986,303,981

Given numbers are 287,321,986,303,981

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

The LCM of 287,321,986,303,981 is 3000080930994.

Find LCM of 287,321,986,303,981 with Prime Factorization


3 287, 321, 986, 303, 981
287, 107, 986, 101, 327

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

3 x 287 x 107 x 986 x 101 x 327 = 3000080930994

Therefore, the lowest common multiple of 287,321,986,303,981 is 3000080930994.

LCM Formula to Find Lowest Common Multiple of 287,321,986,303,981

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.

287 x 321 x 986 x 303 x 981 = 27000728378946

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.

287 : 1, 7, 41, 287

321 : 1, 3, 107, 321

986 : 1, 2, 17, 29, 34, 58, 493, 986

303 : 1, 3, 101, 303

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 287,321,986,303,981, is 1.

Now, the common factors can be found like this.

287:7x 41

321:3x 107

986:2x 17x 29

303:3x 101

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.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 27000728378946/(1x9)

LCM = 27000728378946/9

LCM = 3000080930994

Thus, we can understand that the LCM of 287,321,986,303,981 is 3000080930994.
