Given numbers are 770,421,899,394

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

The LCM of 770,421,899,394 is 57411479510.

Find LCM of 770,421,899,394 with Prime Factorization

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

2 x 385 x 421 x 899 x 197 = 57411479510

Therefore, the lowest common multiple of 770,421,899,394 is 57411479510.

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.

770 x 421 x 899 x 394 = 114822959020

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

421 : 1, 421

899 : 1, 29, 31, 899

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,421,899,394, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

421:421

899:29x 31

394:2x 197

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

2 = 2

Therefore, the value for common factors is 2.

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 = 114822959020/(1x2)

LCM = 114822959020/2

LCM = 57411479510

Thus, we can understand that the LCM of 770,421,899,394 is 57411479510.
