Given numbers are 618,551,103,409

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

The LCM of 618,551,103,409 is 139271862.

Find LCM of 618,551,103,409 with Prime Factorization

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

103 x 6 x 551 x 1 x 409 = 139271862

Therefore, the lowest common multiple of 618,551,103,409 is 139271862.

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 551 x 103 x 409 = 14345001786

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

551 : 1, 19, 29, 551

103 : 1, 103

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,551,103,409, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

551:19x 29

103:103

409:409

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

103 = 103

Therefore, the value for common factors is 103.

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 = 14345001786/(1x103)

LCM = 14345001786/103

LCM = 139271862

Thus, we can understand that the LCM of 618,551,103,409 is 139271862.
