Given numbers are 946,435,437,420

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

The LCM of 946,435,437,420 is 2517618180.

Find LCM of 946,435,437,420 with Prime Factorization

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

2 x 3 x 5 x 473 x 29 x 437 x 14 = 2517618180

Therefore, the lowest common multiple of 946,435,437,420 is 2517618180.

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.

946 x 435 x 437 x 420 = 75528545400

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.

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

435 : 1, 3, 5, 15, 29, 87, 145, 435

437 : 1, 19, 23, 437

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,435,437,420, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

435:3x 5x 29

437:19x 23

420:2x 2x 3x 5x 7

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 75528545400/(1x30)

LCM = 75528545400/30

LCM = 2517618180

Thus, we can understand that the LCM of 946,435,437,420 is 2517618180.
