Given numbers are 642,121,562,266

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

The LCM of 642,121,562,266 is 2903209386.

Find LCM of 642,121,562,266 with Prime Factorization

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

2 x 321 x 121 x 281 x 133 = 2903209386

Therefore, the lowest common multiple of 642,121,562,266 is 2903209386.

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.

642 x 121 x 562 x 266 = 11612837544

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

121 : 1, 11, 121

562 : 1, 2, 281, 562

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,121,562,266, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

121:11x 11

562:2x 281

266:2x 7x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 11612837544/(1x4)

LCM = 11612837544/4

LCM = 2903209386

Thus, we can understand that the LCM of 642,121,562,266 is 2903209386.
