Given numbers are 721,436,689,562

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

The LCM of 721,436,689,562 is 60862150804.

Find LCM of 721,436,689,562 with Prime Factorization

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

2 x 721 x 218 x 689 x 281 = 60862150804

Therefore, the lowest common multiple of 721,436,689,562 is 60862150804.

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.

721 x 436 x 689 x 562 = 121724301608

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.

721 : 1, 7, 103, 721

436 : 1, 2, 4, 109, 218, 436

689 : 1, 13, 53, 689

562 : 1, 2, 281, 562

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,436,689,562, is 1.

Now, the common factors can be found like this.

721:7x 103

436:2x 2x 109

689:13x 53

562:2x 281

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

2 = 2

Therefore, the value for common factors is 2.

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 = 121724301608/(1x2)

LCM = 121724301608/2

LCM = 60862150804

Thus, we can understand that the LCM of 721,436,689,562 is 60862150804.
