Given numbers are 987,671,517,739

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

The LCM of 987,671,517,739 is 489422703.

Find LCM of 987,671,517,739 with Prime Factorization

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

11 x 47 x 21 x 61 x 1 x 739 = 489422703

Therefore, the lowest common multiple of 987,671,517,739 is 489422703.

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 671 x 517 x 739 = 253031537451

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

671 : 1, 11, 61, 671

517 : 1, 11, 47, 517

739 : 1, 739

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,671,517,739, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

671:11x 61

517:11x 47

739:739

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

11x 47 = 517

Therefore, the value for common factors is 517.

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 = 253031537451/(1x517)

LCM = 253031537451/517

LCM = 489422703

Thus, we can understand that the LCM of 987,671,517,739 is 489422703.
