Given numbers are 831,717,728,971,473

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

The LCM of 831,717,728,971,473 is 66406512788616.

Find LCM of 831,717,728,971,473 with Prime Factorization

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

3 x 277 x 239 x 728 x 971 x 473 = 66406512788616

Therefore, the lowest common multiple of 831,717,728,971,473 is 66406512788616.

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.

831 x 717 x 728 x 971 x 473 = 199219538365848

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.

831 : 1, 3, 277, 831

717 : 1, 3, 239, 717

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

971 : 1, 971

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,717,728,971,473, is 1.

Now, the common factors can be found like this.

831:3x 277

717:3x 239

728:2x 2x 2x 7x 13

971:971

473:11x 43

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

3 = 3

Therefore, the value for common factors is 3.

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 = 199219538365848/(1x3)

LCM = 199219538365848/3

LCM = 66406512788616

Thus, we can understand that the LCM of 831,717,728,971,473 is 66406512788616.
