Given numbers are 821,535,272,107

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

The LCM of 821,535,272,107 is 119471920.

Find LCM of 821,535,272,107 with Prime Factorization

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

107 x 821 x 5 x 272 x 1 = 119471920

Therefore, the lowest common multiple of 821,535,272,107 is 119471920.

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 535 x 272 x 107 = 12783495440

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

535 : 1, 5, 107, 535

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,535,272,107, is 1.

Now, the common factors can be found like this.

821:821

535:5x 107

272:2x 2x 2x 2x 17

107:107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 12783495440/(1x107)

LCM = 12783495440/107

LCM = 119471920

Thus, we can understand that the LCM of 821,535,272,107 is 119471920.
