Given numbers are 644,532,497,174,854

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

The LCM of 644,532,497,174,854 is 4610488092.

Find LCM of 644,532,497,174,854 with Prime Factorization

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

2 x 2 x 7 x 23 x 19 x 71 x 87 x 61 = 4610488092

Therefore, the lowest common multiple of 644,532,497,174,854 is 4610488092.

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.

644 x 532 x 497 x 174 x 854 = 25302358648896

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

497 : 1, 7, 71, 497

174 : 1, 2, 3, 6, 29, 58, 87, 174

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,532,497,174,854, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

532:2x 2x 7x 19

497:7x 71

174:2x 3x 29

854:2x 7x 61

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 2x 2x 7x 7x 7 = 5488

Therefore, the value for common factors is 5488.

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 = 25302358648896/(1x5488)

LCM = 25302358648896/5488

LCM = 4610488092

Thus, we can understand that the LCM of 644,532,497,174,854 is 4610488092.
