Given numbers are 774,345,194,780

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

The LCM of 774,345,194,780 is 224483220.

Find LCM of 774,345,194,780 with Prime Factorization

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

2 x 3 x 5 x 129 x 23 x 97 x 26 = 224483220

Therefore, the lowest common multiple of 774,345,194,780 is 224483220.

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.

774 x 345 x 194 x 780 = 40406979600

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

345 : 1, 3, 5, 15, 23, 69, 115, 345

194 : 1, 2, 97, 194

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,345,194,780, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

345:3x 5x 23

194:2x 97

780:2x 2x 3x 5x 13

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 40406979600/(1x180)

LCM = 40406979600/180

LCM = 224483220

Thus, we can understand that the LCM of 774,345,194,780 is 224483220.
