Given numbers are 706,261,221,778,394

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

The LCM of 706,261,221,778,394 is 3120709259538.

Find LCM of 706,261,221,778,394 with Prime Factorization

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

2 x 353 x 261 x 221 x 389 x 197 = 3120709259538

Therefore, the lowest common multiple of 706,261,221,778,394 is 3120709259538.

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.

706 x 261 x 221 x 778 x 394 = 12482837038152

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.

706 : 1, 2, 353, 706

261 : 1, 3, 9, 29, 87, 261

221 : 1, 13, 17, 221

778 : 1, 2, 389, 778

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,261,221,778,394, is 1.

Now, the common factors can be found like this.

706:2x 353

261:3x 3x 29

221:13x 17

778:2x 389

394:2x 197

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 = 12482837038152/(1x4)

LCM = 12482837038152/4

LCM = 3120709259538

Thus, we can understand that the LCM of 706,261,221,778,394 is 3120709259538.
