Given numbers are 763,203,221,861,121

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

The LCM of 763,203,221,861,121 is 72778867161.

Find LCM of 763,203,221,861,121 with Prime Factorization

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

7 x 109 x 29 x 221 x 123 x 121 = 72778867161

Therefore, the lowest common multiple of 763,203,221,861,121 is 72778867161.

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.

763 x 203 x 221 x 861 x 121 = 3566164490889

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.

763 : 1, 7, 109, 763

203 : 1, 7, 29, 203

221 : 1, 13, 17, 221

861 : 1, 3, 7, 21, 41, 123, 287, 861

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,203,221,861,121, is 1.

Now, the common factors can be found like this.

763:7x 109

203:7x 29

221:13x 17

861:3x 7x 41

121:11x 11

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 3566164490889/(1x49)

LCM = 3566164490889/49

LCM = 72778867161

Thus, we can understand that the LCM of 763,203,221,861,121 is 72778867161.
