Given numbers are 389,978,970,434

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

The LCM of 389,978,970,434 is 40039618290.

Find LCM of 389,978,970,434 with Prime Factorization

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

2 x 389 x 489 x 485 x 217 = 40039618290

Therefore, the lowest common multiple of 389,978,970,434 is 40039618290.

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.

389 x 978 x 970 x 434 = 160158473160

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.

389 : 1, 389

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

970 : 1, 2, 5, 10, 97, 194, 485, 970

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,978,970,434, is 1.

Now, the common factors can be found like this.

389:389

978:2x 3x 163

970:2x 5x 97

434:2x 7x 31

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 = 160158473160/(1x4)

LCM = 160158473160/4

LCM = 40039618290

Thus, we can understand that the LCM of 389,978,970,434 is 40039618290.
