Given numbers are 394,640,701,857

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

The LCM of 394,640,701,857 is 75743442560.

Find LCM of 394,640,701,857 with Prime Factorization

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

2 x 197 x 320 x 701 x 857 = 75743442560

Therefore, the lowest common multiple of 394,640,701,857 is 75743442560.

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.

394 x 640 x 701 x 857 = 151486885120

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.

394 : 1, 2, 197, 394

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

701 : 1, 701

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,640,701,857, is 1.

Now, the common factors can be found like this.

394:2x 197

640:2x 2x 2x 2x 2x 2x 2x 5

701:701

857:857

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 = 151486885120/(1x2)

LCM = 151486885120/2

LCM = 75743442560

Thus, we can understand that the LCM of 394,640,701,857 is 75743442560.
