Given numbers are 646,604,266,756,212

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

The LCM of 646,604,266,756,212 is 1954236564.

Find LCM of 646,604,266,756,212 with Prime Factorization

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

2 x 2 x 7 x 19 x 17 x 151 x 1 x 27 x 53 = 1954236564

Therefore, the lowest common multiple of 646,604,266,756,212 is 1954236564.

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 604 x 266 x 756 x 212 = 16634461632768

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

604 : 1, 2, 4, 151, 302, 604

266 : 1, 2, 7, 14, 19, 38, 133, 266

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

212 : 1, 2, 4, 53, 106, 212

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,604,266,756,212, is 2.

Now, the common factors can be found like this.

646:2x 17x 19

604:2x 2x 151

266:2x 7x 19

756:2x 2x 3x 3x 3x 7

212:2x 2x 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 2x 2x 2x 2x 7x 19 = 4256

Therefore, the value for common factors is 4256.

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 = 16634461632768/(2x4256)

LCM = 16634461632768/8512

LCM = 1954236564

Thus, we can understand that the LCM of 646,604,266,756,212 is 1954236564.
