Given numbers are 422,427,211,763

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

The LCM of 422,427,211,763 is 19641146.

Find LCM of 422,427,211,763 with Prime Factorization

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

7 x 211 x 2 x 61 x 1 x 109 = 19641146

Therefore, the lowest common multiple of 422,427,211,763 is 19641146.

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.

422 x 427 x 211 x 763 = 29009972642

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.

422 : 1, 2, 211, 422

427 : 1, 7, 61, 427

211 : 1, 211

763 : 1, 7, 109, 763

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,427,211,763, is 1.

Now, the common factors can be found like this.

422:2x 211

427:7x 61

211:211

763:7x 109

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

7x 211 = 1477

Therefore, the value for common factors is 1477.

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 = 29009972642/(1x1477)

LCM = 29009972642/1477

LCM = 19641146

Thus, we can understand that the LCM of 422,427,211,763 is 19641146.
