Given numbers are 476,316,136,646

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

The LCM of 476,316,136,646 is 1428952.

Find LCM of 476,316,136,646 with Prime Factorization

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

2 x 2 x 17 x 7 x 79 x 2 x 19 = 1428952

Therefore, the lowest common multiple of 476,316,136,646 is 1428952.

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.

476 x 316 x 136 x 646 = 13214948096

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.

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

316 : 1, 2, 4, 79, 158, 316

136 : 1, 2, 4, 8, 17, 34, 68, 136

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,316,136,646, is 2.

Now, the common factors can be found like this.

476:2x 2x 7x 17

316:2x 2x 79

136:2x 2x 2x 17

646:2x 17x 19

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 17x 17 = 4624

Therefore, the value for common factors is 4624.

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 = 13214948096/(2x4624)

LCM = 13214948096/9248

LCM = 1428952

Thus, we can understand that the LCM of 476,316,136,646 is 1428952.
