Given numbers are 920,859,161,786

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

The LCM of 920,859,161,786 is 2174060280.

Find LCM of 920,859,161,786 with Prime Factorization

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

2 x 23 x 20 x 859 x 7 x 393 = 2174060280

Therefore, the lowest common multiple of 920,859,161,786 is 2174060280.

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.

920 x 859 x 161 x 786 = 100006772880

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

859 : 1, 859

161 : 1, 7, 23, 161

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,859,161,786, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

859:859

161:7x 23

786:2x 3x 131

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 100006772880/(1x46)

LCM = 100006772880/46

LCM = 2174060280

Thus, we can understand that the LCM of 920,859,161,786 is 2174060280.
