Given numbers are 798,121,278,161

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

The LCM of 798,121,278,161 is 308695926.

Find LCM of 798,121,278,161 with Prime Factorization

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

2 x 7 x 57 x 121 x 139 x 23 = 308695926

Therefore, the lowest common multiple of 798,121,278,161 is 308695926.

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.

798 x 121 x 278 x 161 = 4321742964

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

121 : 1, 11, 121

278 : 1, 2, 139, 278

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,121,278,161, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

121:11x 11

278:2x 139

161:7x 23

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 4321742964/(1x14)

LCM = 4321742964/14

LCM = 308695926

Thus, we can understand that the LCM of 798,121,278,161 is 308695926.
