Given numbers are 987,715,689,977

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

The LCM of 987,715,689,977 is 36542110605.

Find LCM of 987,715,689,977 with Prime Factorization

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

13 x 987 x 55 x 53 x 977 = 36542110605

Therefore, the lowest common multiple of 987,715,689,977 is 36542110605.

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 715 x 689 x 977 = 475047437865

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

715 : 1, 5, 11, 13, 55, 65, 143, 715

689 : 1, 13, 53, 689

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,715,689,977, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

715:5x 11x 13

689:13x 53

977:977

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

13 = 13

Therefore, the value for common factors is 13.

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 = 475047437865/(1x13)

LCM = 475047437865/13

LCM = 36542110605

Thus, we can understand that the LCM of 987,715,689,977 is 36542110605.
