Given numbers are 772,780,242,109

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

The LCM of 772,780,242,109 is 1985472060.

Find LCM of 772,780,242,109 with Prime Factorization

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

2 x 2 x 193 x 195 x 121 x 109 = 1985472060

Therefore, the lowest common multiple of 772,780,242,109 is 1985472060.

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 780 x 242 x 109 = 15883776480

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

242 : 1, 2, 11, 22, 121, 242

109 : 1, 109

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,780,242,109, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

780:2x 2x 3x 5x 13

242:2x 11x 11

109:109

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 2 = 8

Therefore, the value for common factors is 8.

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 = 15883776480/(1x8)

LCM = 15883776480/8

LCM = 1985472060

Thus, we can understand that the LCM of 772,780,242,109 is 1985472060.
