Given numbers are 121,517,821,761

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

The LCM of 121,517,821,761 is 3553129547.

Find LCM of 121,517,821,761 with Prime Factorization

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

11 x 11 x 47 x 821 x 761 = 3553129547

Therefore, the lowest common multiple of 121,517,821,761 is 3553129547.

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 517 x 821 x 761 = 39084425017

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

517 : 1, 11, 47, 517

821 : 1, 821

761 : 1, 761

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,517,821,761, is 1.

Now, the common factors can be found like this.

121:11x 11

517:11x 47

821:821

761:761

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

11 = 11

Therefore, the value for common factors is 11.

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 = 39084425017/(1x11)

LCM = 39084425017/11

LCM = 3553129547

Thus, we can understand that the LCM of 121,517,821,761 is 3553129547.
