Given numbers are 770,149,394,86

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

The LCM of 770,149,394,86 is 971877830.

Find LCM of 770,149,394,86 with Prime Factorization

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

2 x 385 x 149 x 197 x 43 = 971877830

Therefore, the lowest common multiple of 770,149,394,86 is 971877830.

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 149 x 394 x 86 = 3887511320

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

149 : 1, 149

394 : 1, 2, 197, 394

86 : 1, 2, 43, 86

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,149,394,86, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

149:149

394:2x 197

86:2x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 3887511320/(1x4)

LCM = 3887511320/4

LCM = 971877830

Thus, we can understand that the LCM of 770,149,394,86 is 971877830.
