Given numbers are 121,292,561,782

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

The LCM of 121,292,561,782 is 41444436.

Find LCM of 121,292,561,782 with Prime Factorization

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

2 x 11 x 17 x 11 x 146 x 3 x 23 = 41444436

Therefore, the lowest common multiple of 121,292,561,782 is 41444436.

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 292 x 561 x 782 = 15500219064

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

292 : 1, 2, 4, 73, 146, 292

561 : 1, 3, 11, 17, 33, 51, 187, 561

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,292,561,782, is 1.

Now, the common factors can be found like this.

121:11x 11

292:2x 2x 73

561:3x 11x 17

782:2x 17x 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 11x 17 = 374

Therefore, the value for common factors is 374.

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 = 15500219064/(1x374)

LCM = 15500219064/374

LCM = 41444436

Thus, we can understand that the LCM of 121,292,561,782 is 41444436.
