Given numbers are 781,974,240,970,396

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

The LCM of 781,974,240,970,396 is 26563434480.

Find LCM of 781,974,240,970,396 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 71 x 487 x 4 x 97 x 3 = 26563434480

Therefore, the lowest common multiple of 781,974,240,970,396 is 26563434480.

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.

781 x 974 x 240 x 970 x 396 = 70127467027200

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.

781 : 1, 11, 71, 781

974 : 1, 2, 487, 974

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

970 : 1, 2, 5, 10, 97, 194, 485, 970

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,974,240,970,396, is 1.

Now, the common factors can be found like this.

781:11x 71

974:2x 487

240:2x 2x 2x 2x 3x 5

970:2x 5x 97

396:2x 2x 3x 3x 11

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 3x 5x 11 = 2640

Therefore, the value for common factors is 2640.

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 = 70127467027200/(1x2640)

LCM = 70127467027200/2640

LCM = 26563434480

Thus, we can understand that the LCM of 781,974,240,970,396 is 26563434480.
