Given numbers are 785,135,421

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

The LCM of 785,135,421 is 8923095.

Find LCM of 785,135,421 with Prime Factorization

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

5 x 157 x 27 x 421 = 8923095

Therefore, the lowest common multiple of 785,135,421 is 8923095.

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.

785 x 135 x 421 = 44615475

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.

785 : 1, 5, 157, 785

135 : 1, 3, 5, 9, 15, 27, 45, 135

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,135,421, is 1.

Now, the common factors can be found like this.

785:5x 157

135:3x 3x 3x 5

421:421

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

5 = 5

Therefore, the value for common factors is 5.

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 = 44615475/(1x5)

LCM = 44615475/5

LCM = 8923095

Thus, we can understand that the LCM of 785,135,421 is 8923095.

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

• LCM of 414, 478, 929
• LCM of 578, 988, 302
