Given numbers are 120,479,394,973,387

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

The LCM of 120,479,394,973,387 is 1421299280520.

Find LCM of 120,479,394,973,387 with Prime Factorization

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

2 x 3 x 20 x 479 x 197 x 973 x 129 = 1421299280520

Therefore, the lowest common multiple of 120,479,394,973,387 is 1421299280520.

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.

120 x 479 x 394 x 973 x 387 = 8527795683120

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.

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

479 : 1, 479

394 : 1, 2, 197, 394

973 : 1, 7, 139, 973

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,479,394,973,387, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

479:479

394:2x 197

973:7x 139

387:3x 3x 43

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 8527795683120/(1x6)

LCM = 8527795683120/6

LCM = 1421299280520

Thus, we can understand that the LCM of 120,479,394,973,387 is 1421299280520.
