Given numbers are 637,871,221,619

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

The LCM of 637,871,221,619 is 449111117.

Find LCM of 637,871,221,619 with Prime Factorization

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

13 x 49 x 67 x 17 x 619 = 449111117

Therefore, the lowest common multiple of 637,871,221,619 is 449111117.

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.

637 x 871 x 221 x 619 = 75899778773

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.

637 : 1, 7, 13, 49, 91, 637

871 : 1, 13, 67, 871

221 : 1, 13, 17, 221

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,871,221,619, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

871:13x 67

221:13x 17

619:619

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 75899778773/(1x169)

LCM = 75899778773/169

LCM = 449111117

Thus, we can understand that the LCM of 637,871,221,619 is 449111117.
