Given numbers are 641,895,716,821

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

The LCM of 641,895,716,821 is 1884014380.

Find LCM of 641,895,716,821 with Prime Factorization

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

179 x 641 x 5 x 4 x 821 = 1884014380

Therefore, the lowest common multiple of 641,895,716,821 is 1884014380.

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 895 x 716 x 821 = 337238574020

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

895 : 1, 5, 179, 895

716 : 1, 2, 4, 179, 358, 716

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,895,716,821, is 1.

Now, the common factors can be found like this.

641:641

895:5x 179

716:2x 2x 179

821:821

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

179 = 179

Therefore, the value for common factors is 179.

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 = 337238574020/(1x179)

LCM = 337238574020/179

LCM = 1884014380

Thus, we can understand that the LCM of 641,895,716,821 is 1884014380.
