Given numbers are 856,407,749,305

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

The LCM of 856,407,749,305 is 743816920.

Find LCM of 856,407,749,305 with Prime Factorization

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

107 x 8 x 407 x 7 x 305 = 743816920

Therefore, the lowest common multiple of 856,407,749,305 is 743816920.

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.

856 x 407 x 749 x 305 = 79588410440

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

407 : 1, 11, 37, 407

749 : 1, 7, 107, 749

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,407,749,305, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

407:11x 37

749:7x 107

305:5x 61

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 = 79588410440/(1x107)

LCM = 79588410440/107

LCM = 743816920

Thus, we can understand that the LCM of 856,407,749,305 is 743816920.
