Given numbers are 161,975,769,442

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

The LCM of 161,975,769,442 is 4104268350.

Find LCM of 161,975,769,442 with Prime Factorization

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

13 x 161 x 75 x 769 x 34 = 4104268350

Therefore, the lowest common multiple of 161,975,769,442 is 4104268350.

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.

161 x 975 x 769 x 442 = 53355488550

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.

161 : 1, 7, 23, 161

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

769 : 1, 769

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,975,769,442, is 1.

Now, the common factors can be found like this.

161:7x 23

975:3x 5x 5x 13

769:769

442:2x 13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 53355488550/(1x13)

LCM = 53355488550/13

LCM = 4104268350

Thus, we can understand that the LCM of 161,975,769,442 is 4104268350.
