Given numbers are 678,916,421,655

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

The LCM of 678,916,421,655 is 85628545620.

Find LCM of 678,916,421,655 with Prime Factorization

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

2 x 339 x 458 x 421 x 655 = 85628545620

Therefore, the lowest common multiple of 678,916,421,655 is 85628545620.

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.

678 x 916 x 421 x 655 = 171257091240

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.

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

916 : 1, 2, 4, 229, 458, 916

421 : 1, 421

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,916,421,655, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

916:2x 2x 229

421:421

655:5x 131

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

2 = 2

Therefore, the value for common factors is 2.

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 = 171257091240/(1x2)

LCM = 171257091240/2

LCM = 85628545620

Thus, we can understand that the LCM of 678,916,421,655 is 85628545620.
