Given numbers are 391,946,235,418

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

The LCM of 391,946,235,418 is 1651540990.

Find LCM of 391,946,235,418 with Prime Factorization

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

2 x 11 x 391 x 43 x 235 x 19 = 1651540990

Therefore, the lowest common multiple of 391,946,235,418 is 1651540990.

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.

391 x 946 x 235 x 418 = 36333901780

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.

391 : 1, 17, 23, 391

946 : 1, 2, 11, 22, 43, 86, 473, 946

235 : 1, 5, 47, 235

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,946,235,418, is 1.

Now, the common factors can be found like this.

391:17x 23

946:2x 11x 43

235:5x 47

418:2x 11x 19

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 = 36333901780/(1x22)

LCM = 36333901780/22

LCM = 1651540990

Thus, we can understand that the LCM of 391,946,235,418 is 1651540990.
