Given numbers are 121,420,692,770,478

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

The LCM of 121,420,692,770,478 is 2101254540.

Find LCM of 121,420,692,770,478 with Prime Factorization

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

2 x 2 x 5 x 7 x 11 x 1 x 3 x 173 x 11 x 239 = 2101254540

Therefore, the lowest common multiple of 121,420,692,770,478 is 2101254540.

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 420 x 692 x 770 x 478 = 12943727966400

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

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

692 : 1, 2, 4, 173, 346, 692

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,420,692,770,478, is 1.

Now, the common factors can be found like this.

121:11x 11

420:2x 2x 3x 5x 7

692:2x 2x 173

770:2x 5x 7x 11

478:2x 239

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 5x 7x 11 = 6160

Therefore, the value for common factors is 6160.

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 = 12943727966400/(1x6160)

LCM = 12943727966400/6160

LCM = 2101254540

Thus, we can understand that the LCM of 121,420,692,770,478 is 2101254540.
