Given numbers are 322,178,620,121

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

The LCM of 322,178,620,121 is 1074961580.

Find LCM of 322,178,620,121 with Prime Factorization

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

2 x 161 x 89 x 310 x 121 = 1074961580

Therefore, the lowest common multiple of 322,178,620,121 is 1074961580.

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.

322 x 178 x 620 x 121 = 4299846320

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.

322 : 1, 2, 7, 14, 23, 46, 161, 322

178 : 1, 2, 89, 178

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,178,620,121, is 1.

Now, the common factors can be found like this.

322:2x 7x 23

178:2x 89

620:2x 2x 5x 31

121:11x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 4299846320/(1x4)

LCM = 4299846320/4

LCM = 1074961580

Thus, we can understand that the LCM of 322,178,620,121 is 1074961580.
