Given numbers are 646,629,247,636

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

The LCM of 646,629,247,636 is 98810868.

Find LCM of 646,629,247,636 with Prime Factorization

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

2 x 17 x 19 x 1 x 37 x 13 x 318 = 98810868

Therefore, the lowest common multiple of 646,629,247,636 is 98810868.

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.

646 x 629 x 247 x 636 = 63831820728

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

629 : 1, 17, 37, 629

247 : 1, 13, 19, 247

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,629,247,636, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

629:17x 37

247:13x 19

636:2x 2x 3x 53

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

2x 17x 19 = 646

Therefore, the value for common factors is 646.

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 = 63831820728/(1x646)

LCM = 63831820728/646

LCM = 98810868

Thus, we can understand that the LCM of 646,629,247,636 is 98810868.
