Given numbers are 637,203,987,356,668

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

The LCM of 637,203,987,356,668 is 154854208236.

Find LCM of 637,203,987,356,668 with Prime Factorization

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

2 x 2 x 7 x 91 x 29 x 141 x 89 x 167 = 154854208236

Therefore, the lowest common multiple of 637,203,987,356,668 is 154854208236.

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.

637 x 203 x 987 x 356 x 668 = 30351424814256

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.

637 : 1, 7, 13, 49, 91, 637

203 : 1, 7, 29, 203

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

356 : 1, 2, 4, 89, 178, 356

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,203,987,356,668, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

203:7x 29

987:3x 7x 47

356:2x 2x 89

668:2x 2x 167

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

2x 2x 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 30351424814256/(1x196)

LCM = 30351424814256/196

LCM = 154854208236

Thus, we can understand that the LCM of 637,203,987,356,668 is 154854208236.
