Given numbers are 103,515,421,307

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

The LCM of 103,515,421,307 is 66562205.

Find LCM of 103,515,421,307 with Prime Factorization

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

103 x 1 x 5 x 421 x 307 = 66562205

Therefore, the lowest common multiple of 103,515,421,307 is 66562205.

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.

103 x 515 x 421 x 307 = 6855907115

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.

103 : 1, 103

515 : 1, 5, 103, 515

421 : 1, 421

307 : 1, 307

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,515,421,307, is 1.

Now, the common factors can be found like this.

103:103

515:5x 103

421:421

307:307

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 = 6855907115/(1x103)

LCM = 6855907115/103

LCM = 66562205

Thus, we can understand that the LCM of 103,515,421,307 is 66562205.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 623, 978, 289, 638
