Given numbers are 121,528,274,752,921

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

The LCM of 121,528,274,752,921 is 11481097584.

Find LCM of 121,528,274,752,921 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 11 x 1 x 11 x 137 x 47 x 307 = 11481097584

Therefore, the lowest common multiple of 121,528,274,752,921 is 11481097584.

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 528 x 274 x 752 x 921 = 12124039048704

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

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

274 : 1, 2, 137, 274

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,528,274,752,921, is 1.

Now, the common factors can be found like this.

121:11x 11

528:2x 2x 2x 2x 3x 11

274:2x 137

752:2x 2x 2x 2x 47

921:3x 307

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 2x 2x 3x 11 = 1056

Therefore, the value for common factors is 1056.

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 = 12124039048704/(1x1056)

LCM = 12124039048704/1056

LCM = 11481097584

Thus, we can understand that the LCM of 121,528,274,752,921 is 11481097584.
