Given numbers are 641,782,537,218

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

The LCM of 641,782,537,218 is 29340368646.

Find LCM of 641,782,537,218 with Prime Factorization

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

2 x 641 x 391 x 537 x 109 = 29340368646

Therefore, the lowest common multiple of 641,782,537,218 is 29340368646.

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.

641 x 782 x 537 x 218 = 58680737292

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.

641 : 1, 641

782 : 1, 2, 17, 23, 34, 46, 391, 782

537 : 1, 3, 179, 537

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,782,537,218, is 1.

Now, the common factors can be found like this.

641:641

782:2x 17x 23

537:3x 179

218:2x 109

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

2 = 2

Therefore, the value for common factors is 2.

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 = 58680737292/(1x2)

LCM = 58680737292/2

LCM = 29340368646

Thus, we can understand that the LCM of 641,782,537,218 is 29340368646.
