Given numbers are 394,968,145,561

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

The LCM of 394,968,145,561 is 1410196920.

Find LCM of 394,968,145,561 with Prime Factorization

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

2 x 11 x 197 x 44 x 145 x 51 = 1410196920

Therefore, the lowest common multiple of 394,968,145,561 is 1410196920.

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 968 x 145 x 561 = 31024332240

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

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

145 : 1, 5, 29, 145

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,968,145,561, is 1.

Now, the common factors can be found like this.

394:2x 197

968:2x 2x 2x 11x 11

145:5x 29

561:3x 11x 17

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 31024332240/(1x22)

LCM = 31024332240/22

LCM = 1410196920

Thus, we can understand that the LCM of 394,968,145,561 is 1410196920.
