Given numbers are 121,438,322,830,876

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

The LCM of 121,438,322,830,876 is 7082122740.

Find LCM of 121,438,322,830,876 with Prime Factorization

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

2 x 3 x 73 x 121 x 1 x 161 x 415 x 2 = 7082122740

Therefore, the lowest common multiple of 121,438,322,830,876 is 7082122740.

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.

121 x 438 x 322 x 830 x 876 = 12407879040480

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.

121 : 1, 11, 121

438 : 1, 2, 3, 6, 73, 146, 219, 438

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

830 : 1, 2, 5, 10, 83, 166, 415, 830

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,438,322,830,876, is 1.

Now, the common factors can be found like this.

121:11x 11

438:2x 3x 73

322:2x 7x 23

830:2x 5x 83

876:2x 2x 3x 73

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 2x 3x 73 = 1752

Therefore, the value for common factors is 1752.

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 = 12407879040480/(1x1752)

LCM = 12407879040480/1752

LCM = 7082122740

Thus, we can understand that the LCM of 121,438,322,830,876 is 7082122740.
