Given numbers are 974,455,819,457

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

The LCM of 974,455,819,457 is 1822758210.

Find LCM of 974,455,819,457 with Prime Factorization

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

7 x 13 x 974 x 5 x 9 x 457 = 1822758210

Therefore, the lowest common multiple of 974,455,819,457 is 1822758210.

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.

974 x 455 x 819 x 457 = 165870997110

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.

974 : 1, 2, 487, 974

455 : 1, 5, 7, 13, 35, 65, 91, 455

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,455,819,457, is 1.

Now, the common factors can be found like this.

974:2x 487

455:5x 7x 13

819:3x 3x 7x 13

457:457

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

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 165870997110/(1x91)

LCM = 165870997110/91

LCM = 1822758210

Thus, we can understand that the LCM of 974,455,819,457 is 1822758210.
