Given numbers are 791,221,452,913

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

The LCM of 791,221,452,913 is 638409772.

Find LCM of 791,221,452,913 with Prime Factorization

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

113 x 7 x 221 x 4 x 913 = 638409772

Therefore, the lowest common multiple of 791,221,452,913 is 638409772.

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.

791 x 221 x 452 x 913 = 72140304236

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.

791 : 1, 7, 113, 791

221 : 1, 13, 17, 221

452 : 1, 2, 4, 113, 226, 452

913 : 1, 11, 83, 913

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,221,452,913, is 1.

Now, the common factors can be found like this.

791:7x 113

221:13x 17

452:2x 2x 113

913:11x 83

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

113 = 113

Therefore, the value for common factors is 113.

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 = 72140304236/(1x113)

LCM = 72140304236/113

LCM = 638409772

Thus, we can understand that the LCM of 791,221,452,913 is 638409772.
