Given numbers are 618,430,813,644,374

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

The LCM of 618,430,813,644,374 is 2168171862780.

Find LCM of 618,430,813,644,374 with Prime Factorization

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

2 x 3 x 103 x 215 x 271 x 322 x 187 = 2168171862780

Therefore, the lowest common multiple of 618,430,813,644,374 is 2168171862780.

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.

618 x 430 x 813 x 644 x 374 = 52036124706720

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

430 : 1, 2, 5, 10, 43, 86, 215, 430

813 : 1, 3, 271, 813

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

374 : 1, 2, 11, 17, 22, 34, 187, 374

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,430,813,644,374, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

430:2x 5x 43

813:3x 271

644:2x 2x 7x 23

374:2x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 52036124706720/(1x24)

LCM = 52036124706720/24

LCM = 2168171862780

Thus, we can understand that the LCM of 618,430,813,644,374 is 2168171862780.
