Given numbers are 712,445,749,689

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

The LCM of 712,445,749,689 is 1837177160.

Find LCM of 712,445,749,689 with Prime Factorization

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

89 x 8 x 5 x 749 x 689 = 1837177160

Therefore, the lowest common multiple of 712,445,749,689 is 1837177160.

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.

712 x 445 x 749 x 689 = 163508767240

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.

712 : 1, 2, 4, 8, 89, 178, 356, 712

445 : 1, 5, 89, 445

749 : 1, 7, 107, 749

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,445,749,689, is 1.

Now, the common factors can be found like this.

712:2x 2x 2x 89

445:5x 89

749:7x 107

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.

89 = 89

Therefore, the value for common factors is 89.

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 = 163508767240/(1x89)

LCM = 163508767240/89

LCM = 1837177160

Thus, we can understand that the LCM of 712,445,749,689 is 1837177160.
