Given numbers are 121,322,437,639

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

The LCM of 121,322,437,639 is 473037642.

Find LCM of 121,322,437,639 with Prime Factorization

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

23 x 121 x 14 x 19 x 639 = 473037642

Therefore, the lowest common multiple of 121,322,437,639 is 473037642.

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 322 x 437 x 639 = 10879865766

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

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

437 : 1, 19, 23, 437

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,322,437,639, is 1.

Now, the common factors can be found like this.

121:11x 11

322:2x 7x 23

437:19x 23

639:3x 3x 71

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

23 = 23

Therefore, the value for common factors is 23.

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 = 10879865766/(1x23)

LCM = 10879865766/23

LCM = 473037642

Thus, we can understand that the LCM of 121,322,437,639 is 473037642.
