Given numbers are 987,614,986,538

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

The LCM of 987,614,986,538 is 80368289106.

Find LCM of 987,614,986,538 with Prime Factorization

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

2 x 987 x 307 x 493 x 269 = 80368289106

Therefore, the lowest common multiple of 987,614,986,538 is 80368289106.

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.

987 x 614 x 986 x 538 = 321473156424

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

614 : 1, 2, 307, 614

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

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,614,986,538, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

614:2x 307

986:2x 17x 29

538:2x 269

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 321473156424/(1x4)

LCM = 321473156424/4

LCM = 80368289106

Thus, we can understand that the LCM of 987,614,986,538 is 80368289106.
