Given numbers are 121,373,228,871,689

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

The LCM of 121,373,228,871,689 is 475032226812.

Find LCM of 121,373,228,871,689 with Prime Factorization

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

13 x 121 x 373 x 228 x 67 x 53 = 475032226812

Therefore, the lowest common multiple of 121,373,228,871,689 is 475032226812.

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.

121 x 373 x 228 x 871 x 689 = 6175418948556

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.

121 : 1, 11, 121

373 : 1, 373

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

871 : 1, 13, 67, 871

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,373,228,871,689, is 1.

Now, the common factors can be found like this.

121:11x 11

373:373

228:2x 2x 3x 19

871:13x 67

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 6175418948556/(1x13)

LCM = 6175418948556/13

LCM = 475032226812

Thus, we can understand that the LCM of 121,373,228,871,689 is 475032226812.
