Given numbers are 869,716,128,434

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

The LCM of 869,716,128,434 is 4320584576.

Find LCM of 869,716,128,434 with Prime Factorization

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

2 x 2 x 869 x 179 x 32 x 217 = 4320584576

Therefore, the lowest common multiple of 869,716,128,434 is 4320584576.

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.

869 x 716 x 128 x 434 = 34564676608

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.

869 : 1, 11, 79, 869

716 : 1, 2, 4, 179, 358, 716

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

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,716,128,434, is 1.

Now, the common factors can be found like this.

869:11x 79

716:2x 2x 179

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

434:2x 7x 31

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 34564676608/(1x8)

LCM = 34564676608/8

LCM = 4320584576

Thus, we can understand that the LCM of 869,716,128,434 is 4320584576.
