Given numbers are 987,214,248,639

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

The LCM of 987,214,248,639 is 5578689816.

Find LCM of 987,214,248,639 with Prime Factorization

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

2 x 3 x 329 x 107 x 124 x 213 = 5578689816

Therefore, the lowest common multiple of 987,214,248,639 is 5578689816.

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 214 x 248 x 639 = 33472138896

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

214 : 1, 2, 107, 214

248 : 1, 2, 4, 8, 31, 62, 124, 248

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,214,248,639, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

214:2x 107

248:2x 2x 2x 31

639:3x 3x 71

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 33472138896/(1x6)

LCM = 33472138896/6

LCM = 5578689816

Thus, we can understand that the LCM of 987,214,248,639 is 5578689816.
