Given numbers are 771,227,987,790

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

The LCM of 771,227,987,790 is 45488668470.

Find LCM of 771,227,987,790 with Prime Factorization

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

3 x 257 x 227 x 329 x 790 = 45488668470

Therefore, the lowest common multiple of 771,227,987,790 is 45488668470.

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.

771 x 227 x 987 x 790 = 136466005410

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.

771 : 1, 3, 257, 771

227 : 1, 227

987 : 1, 3, 7, 21, 47, 141, 329, 987

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,227,987,790, is 1.

Now, the common factors can be found like this.

771:3x 257

227:227

987:3x 7x 47

790:2x 5x 79

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

3 = 3

Therefore, the value for common factors is 3.

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 = 136466005410/(1x3)

LCM = 136466005410/3

LCM = 45488668470

Thus, we can understand that the LCM of 771,227,987,790 is 45488668470.
