Given numbers are 749,943,991,644

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

The LCM of 749,943,991,644 is 2799800948.

Find LCM of 749,943,991,644 with Prime Factorization

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

7 x 23 x 107 x 41 x 991 x 4 = 2799800948

Therefore, the lowest common multiple of 749,943,991,644 is 2799800948.

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.

749 x 943 x 991 x 644 = 450767952628

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.

749 : 1, 7, 107, 749

943 : 1, 23, 41, 943

991 : 1, 991

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,943,991,644, is 1.

Now, the common factors can be found like this.

749:7x 107

943:23x 41

991:991

644:2x 2x 7x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 450767952628/(1x161)

LCM = 450767952628/161

LCM = 2799800948

Thus, we can understand that the LCM of 749,943,991,644 is 2799800948.
