Given numbers are 661,987,633,664

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

The LCM of 661,987,633,664 is 91404830328.

Find LCM of 661,987,633,664 with Prime Factorization

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

3 x 661 x 329 x 211 x 664 = 91404830328

Therefore, the lowest common multiple of 661,987,633,664 is 91404830328.

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.

661 x 987 x 633 x 664 = 274214490984

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.

661 : 1, 661

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

633 : 1, 3, 211, 633

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,987,633,664, is 1.

Now, the common factors can be found like this.

661:661

987:3x 7x 47

633:3x 211

664:2x 2x 2x 83

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

3 = 3

Therefore, the value for common factors is 3.

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 = 274214490984/(1x3)

LCM = 274214490984/3

LCM = 91404830328

Thus, we can understand that the LCM of 661,987,633,664 is 91404830328.
