Given numbers are 565,403,418,438

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

The LCM of 565,403,418,438 is 20843655690.

Find LCM of 565,403,418,438 with Prime Factorization

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

2 x 565 x 403 x 209 x 219 = 20843655690

Therefore, the lowest common multiple of 565,403,418,438 is 20843655690.

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.

565 x 403 x 418 x 438 = 41687311380

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.

565 : 1, 5, 113, 565

403 : 1, 13, 31, 403

418 : 1, 2, 11, 19, 22, 38, 209, 418

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,403,418,438, is 1.

Now, the common factors can be found like this.

565:5x 113

403:13x 31

418:2x 11x 19

438:2x 3x 73

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

2 = 2

Therefore, the value for common factors is 2.

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 = 41687311380/(1x2)

LCM = 41687311380/2

LCM = 20843655690

Thus, we can understand that the LCM of 565,403,418,438 is 20843655690.
