Given numbers are 421,386,909,922

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

The LCM of 421,386,909,922 is 68097976794.

Find LCM of 421,386,909,922 with Prime Factorization

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

2 x 421 x 193 x 909 x 461 = 68097976794

Therefore, the lowest common multiple of 421,386,909,922 is 68097976794.

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.

421 x 386 x 909 x 922 = 136195953588

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.

421 : 1, 421

386 : 1, 2, 193, 386

909 : 1, 3, 9, 101, 303, 909

922 : 1, 2, 461, 922

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,386,909,922, is 1.

Now, the common factors can be found like this.

421:421

386:2x 193

909:3x 3x 101

922:2x 461

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

2 = 2

Therefore, the value for common factors is 2.

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 = 136195953588/(1x2)

LCM = 136195953588/2

LCM = 68097976794

Thus, we can understand that the LCM of 421,386,909,922 is 68097976794.

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