Given numbers are 978,393,604,473,915

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

The LCM of 978,393,604,473,915 is 5581848867540.

Find LCM of 978,393,604,473,915 with Prime Factorization

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

2 x 3 x 163 x 131 x 302 x 473 x 305 = 5581848867540

Therefore, the lowest common multiple of 978,393,604,473,915 is 5581848867540.

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.

978 x 393 x 604 x 473 x 915 = 100473279615720

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.

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

393 : 1, 3, 131, 393

604 : 1, 2, 4, 151, 302, 604

473 : 1, 11, 43, 473

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,393,604,473,915, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

393:3x 131

604:2x 2x 151

473:11x 43

915:3x 5x 61

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 100473279615720/(1x18)

LCM = 100473279615720/18

LCM = 5581848867540

Thus, we can understand that the LCM of 978,393,604,473,915 is 5581848867540.
