Given numbers are 770,422,560,427

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

The LCM of 770,422,560,427 is 79285360.

Find LCM of 770,422,560,427 with Prime Factorization

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

2 x 5 x 7 x 11 x 211 x 8 x 61 = 79285360

Therefore, the lowest common multiple of 770,422,560,427 is 79285360.

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.

770 x 422 x 560 x 427 = 77699652800

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

422 : 1, 2, 211, 422

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,422,560,427, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

422:2x 211

560:2x 2x 2x 2x 5x 7

427:7x 61

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 5x 7x 7 = 980

Therefore, the value for common factors is 980.

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 = 77699652800/(1x980)

LCM = 77699652800/980

LCM = 79285360

Thus, we can understand that the LCM of 770,422,560,427 is 79285360.
