Given numbers are 678,635,248,85

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

The LCM of 678,635,248,85 is 907557240.

Find LCM of 678,635,248,85 with Prime Factorization

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

2 x 5 x 339 x 127 x 124 x 17 = 907557240

Therefore, the lowest common multiple of 678,635,248,85 is 907557240.

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 635 x 248 x 85 = 9075572400

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

635 : 1, 5, 127, 635

248 : 1, 2, 4, 8, 31, 62, 124, 248

85 : 1, 5, 17, 85

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,635,248,85, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

635:5x 127

248:2x 2x 2x 31

85:5x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 9075572400/(1x10)

LCM = 9075572400/10

LCM = 907557240

Thus, we can understand that the LCM of 678,635,248,85 is 907557240.
