Given numbers are 428,539,726,743,121

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

The LCM of 428,539,726,743,121 is 5656337148.

Find LCM of 428,539,726,743,121 with Prime Factorization

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

2 x 11 x 11 x 214 x 49 x 3 x 743 x 1 = 5656337148

Therefore, the lowest common multiple of 428,539,726,743,121 is 5656337148.

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.

428 x 539 x 726 x 743 x 121 = 15057169487976

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.

428 : 1, 2, 4, 107, 214, 428

539 : 1, 7, 11, 49, 77, 539

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

743 : 1, 743

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,539,726,743,121, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

539:7x 7x 11

726:2x 3x 11x 11

743:743

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.

2x 11x 11x 11 = 2662

Therefore, the value for common factors is 2662.

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 = 15057169487976/(1x2662)

LCM = 15057169487976/2662

LCM = 5656337148

Thus, we can understand that the LCM of 428,539,726,743,121 is 5656337148.
