Given numbers are 635,978,428,485

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

The LCM of 635,978,428,485 is 12891340740.

Find LCM of 635,978,428,485 with Prime Factorization

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

2 x 5 x 127 x 489 x 214 x 97 = 12891340740

Therefore, the lowest common multiple of 635,978,428,485 is 12891340740.

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.

635 x 978 x 428 x 485 = 128913407400

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.

635 : 1, 5, 127, 635

978 : 1, 2, 3, 6, 163, 326, 489, 978

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

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,978,428,485, is 1.

Now, the common factors can be found like this.

635:5x 127

978:2x 3x 163

428:2x 2x 107

485:5x 97

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 = 128913407400/(1x10)

LCM = 128913407400/10

LCM = 12891340740

Thus, we can understand that the LCM of 635,978,428,485 is 12891340740.
