Given numbers are 386,221,122,786

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

The LCM of 386,221,122,786 is 2045040738.

Find LCM of 386,221,122,786 with Prime Factorization

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

2 x 193 x 221 x 61 x 393 = 2045040738

Therefore, the lowest common multiple of 386,221,122,786 is 2045040738.

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.

386 x 221 x 122 x 786 = 8180162952

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.

386 : 1, 2, 193, 386

221 : 1, 13, 17, 221

122 : 1, 2, 61, 122

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,221,122,786, is 1.

Now, the common factors can be found like this.

386:2x 193

221:13x 17

122:2x 61

786:2x 3x 131

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 = 8180162952/(1x4)

LCM = 8180162952/4

LCM = 2045040738

Thus, we can understand that the LCM of 386,221,122,786 is 2045040738.
