Given numbers are 821,545,981,919

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

The LCM of 821,545,981,919 is 3700817595.

Find LCM of 821,545,981,919 with Prime Factorization

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

109 x 821 x 5 x 9 x 919 = 3700817595

Therefore, the lowest common multiple of 821,545,981,919 is 3700817595.

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.

821 x 545 x 981 x 919 = 403389117855

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.

821 : 1, 821

545 : 1, 5, 109, 545

981 : 1, 3, 9, 109, 327, 981

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,545,981,919, is 1.

Now, the common factors can be found like this.

821:821

545:5x 109

981:3x 3x 109

919:919

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

109 = 109

Therefore, the value for common factors is 109.

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 = 403389117855/(1x109)

LCM = 403389117855/109

LCM = 3700817595

Thus, we can understand that the LCM of 821,545,981,919 is 3700817595.
