Given numbers are 987,122,856,398

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

The LCM of 987,122,856,398 is 10255901208.

Find LCM of 987,122,856,398 with Prime Factorization

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

2 x 987 x 61 x 428 x 199 = 10255901208

Therefore, the lowest common multiple of 987,122,856,398 is 10255901208.

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 122 x 856 x 398 = 41023604832

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

122 : 1, 2, 61, 122

856 : 1, 2, 4, 8, 107, 214, 428, 856

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,122,856,398, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

122:2x 61

856:2x 2x 2x 107

398:2x 199

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 = 41023604832/(1x4)

LCM = 41023604832/4

LCM = 10255901208

Thus, we can understand that the LCM of 987,122,856,398 is 10255901208.
