Given numbers are 646,964,649,622

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

The LCM of 646,964,649,622 is 62847013108.

Find LCM of 646,964,649,622 with Prime Factorization

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

2 x 323 x 482 x 649 x 311 = 62847013108

Therefore, the lowest common multiple of 646,964,649,622 is 62847013108.

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 964 x 649 x 622 = 251388052432

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

964 : 1, 2, 4, 241, 482, 964

649 : 1, 11, 59, 649

622 : 1, 2, 311, 622

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,964,649,622, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

964:2x 2x 241

649:11x 59

622:2x 311

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 251388052432/(1x4)

LCM = 251388052432/4

LCM = 62847013108

Thus, we can understand that the LCM of 646,964,649,622 is 62847013108.
