Given numbers are 772,170,119,442

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

The LCM of 772,170,119,442 is 5971420.

Find LCM of 772,170,119,442 with Prime Factorization

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

2 x 17 x 386 x 5 x 7 x 13 = 5971420

Therefore, the lowest common multiple of 772,170,119,442 is 5971420.

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.

772 x 170 x 119 x 442 = 6902961520

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.

772 : 1, 2, 4, 193, 386, 772

170 : 1, 2, 5, 10, 17, 34, 85, 170

119 : 1, 7, 17, 119

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 772,170,119,442, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

170:2x 5x 17

119:7x 17

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.

2x 2x 17x 17 = 1156

Therefore, the value for common factors is 1156.

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 = 6902961520/(1x1156)

LCM = 6902961520/1156

LCM = 5971420

Thus, we can understand that the LCM of 772,170,119,442 is 5971420.
