Given numbers are 420,874,209,629

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

The LCM of 420,874,209,629 is 1269913260.

Find LCM of 420,874,209,629 with Prime Factorization

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

2 x 19 x 210 x 23 x 11 x 629 = 1269913260

Therefore, the lowest common multiple of 420,874,209,629 is 1269913260.

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.

420 x 874 x 209 x 629 = 48256703880

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.

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

874 : 1, 2, 19, 23, 38, 46, 437, 874

209 : 1, 11, 19, 209

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,874,209,629, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

874:2x 19x 23

209:11x 19

629:17x 37

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 48256703880/(1x38)

LCM = 48256703880/38

LCM = 1269913260

Thus, we can understand that the LCM of 420,874,209,629 is 1269913260.
