Given numbers are 856,770,161,581

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

The LCM of 856,770,161,581 is 629130040.

Find LCM of 856,770,161,581 with Prime Factorization

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

2 x 7 x 428 x 55 x 23 x 83 = 629130040

Therefore, the lowest common multiple of 856,770,161,581 is 629130040.

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.

856 x 770 x 161 x 581 = 61654743920

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

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

161 : 1, 7, 23, 161

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,770,161,581, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

770:2x 5x 7x 11

161:7x 23

581:7x 83

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 61654743920/(1x98)

LCM = 61654743920/98

LCM = 629130040

Thus, we can understand that the LCM of 856,770,161,581 is 629130040.

Here are some samples of LCM of two or more Numbers calculations.
