Given numbers are 772,172,388,440,220

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

The LCM of 772,172,388,440,220 is 354201320.

Find LCM of 772,172,388,440,220 with Prime Factorization

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

2 x 2 x 5 x 11 x 193 x 43 x 97 x 1 x 2 = 354201320

Therefore, the lowest common multiple of 772,172,388,440,220 is 354201320.

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.

772 x 172 x 388 x 440 x 220 = 4987154585600

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.

772 : 1, 2, 4, 193, 386, 772

172 : 1, 2, 4, 43, 86, 172

388 : 1, 2, 4, 97, 194, 388

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,172,388,440,220, is 4.

Now, the common factors can be found like this.

772:2x 2x 193

172:2x 2x 43

388:2x 2x 97

440:2x 2x 2x 5x 11

220:2x 2x 5x 11

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

2x 2x 2x 2x 2x 2x 5x 11 = 3520

Therefore, the value for common factors is 3520.

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 = 4987154585600/(4x3520)

LCM = 4987154585600/14080

LCM = 354201320

Thus, we can understand that the LCM of 772,172,388,440,220 is 354201320.
