Given numbers are 903,559,121,689

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

The LCM of 903,559,121,689 is 75282207.

Find LCM of 903,559,121,689 with Prime Factorization

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

13 x 43 x 21 x 1 x 121 x 53 = 75282207

Therefore, the lowest common multiple of 903,559,121,689 is 75282207.

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.

903 x 559 x 121 x 689 = 42082753713

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

559 : 1, 13, 43, 559

121 : 1, 11, 121

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,559,121,689, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

559:13x 43

121:11x 11

689:13x 53

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

13x 43 = 559

Therefore, the value for common factors is 559.

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 = 42082753713/(1x559)

LCM = 42082753713/559

LCM = 75282207

Thus, we can understand that the LCM of 903,559,121,689 is 75282207.
