Given numbers are 856,829,678,578

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

The LCM of 856,829,678,578 is 69522572904.

Find LCM of 856,829,678,578 with Prime Factorization

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

2 x 428 x 829 x 339 x 289 = 69522572904

Therefore, the lowest common multiple of 856,829,678,578 is 69522572904.

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 829 x 678 x 578 = 278090291616

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

829 : 1, 829

678 : 1, 2, 3, 6, 113, 226, 339, 678

578 : 1, 2, 17, 34, 289, 578

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,829,678,578, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

829:829

678:2x 3x 113

578:2x 17x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 278090291616/(1x4)

LCM = 278090291616/4

LCM = 69522572904

Thus, we can understand that the LCM of 856,829,678,578 is 69522572904.
