Given numbers are 791,785,128,942

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

The LCM of 791,785,128,942 is 238439040.

Find LCM of 791,785,128,942 with Prime Factorization

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

2 x 157 x 791 x 5 x 64 x 3 = 238439040

Therefore, the lowest common multiple of 791,785,128,942 is 238439040.

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 785 x 128 x 942 = 74869858560

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

785 : 1, 5, 157, 785

128 : 1, 2, 4, 8, 16, 32, 64, 128

942 : 1, 2, 3, 6, 157, 314, 471, 942

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,785,128,942, is 1.

Now, the common factors can be found like this.

791:7x 113

785:5x 157

128:2x 2x 2x 2x 2x 2x 2

942:2x 3x 157

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 74869858560/(1x314)

LCM = 74869858560/314

LCM = 238439040

Thus, we can understand that the LCM of 791,785,128,942 is 238439040.
