Given numbers are 778,412,421,161,326

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

The LCM of 778,412,421,161,326 is 1770689425204.

Find LCM of 778,412,421,161,326 with Prime Factorization

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

2 x 389 x 206 x 421 x 161 x 163 = 1770689425204

Therefore, the lowest common multiple of 778,412,421,161,326 is 1770689425204.

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.

778 x 412 x 421 x 161 x 326 = 7082757700816

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.

778 : 1, 2, 389, 778

412 : 1, 2, 4, 103, 206, 412

421 : 1, 421

161 : 1, 7, 23, 161

326 : 1, 2, 163, 326

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,412,421,161,326, is 1.

Now, the common factors can be found like this.

778:2x 389

412:2x 2x 103

421:421

161:7x 23

326:2x 163

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 7082757700816/(1x4)

LCM = 7082757700816/4

LCM = 1770689425204

Thus, we can understand that the LCM of 778,412,421,161,326 is 1770689425204.
