Given numbers are 974,840,112,697

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

The LCM of 974,840,112,697 is 570257520.

Find LCM of 974,840,112,697 with Prime Factorization

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

2 x 2 x 2 x 7 x 487 x 15 x 2 x 697 = 570257520

Therefore, the lowest common multiple of 974,840,112,697 is 570257520.

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 840 x 112 x 697 = 63868842240

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,840,112,697, is 1.

Now, the common factors can be found like this.

974:2x 487

840:2x 2x 2x 3x 5x 7

112:2x 2x 2x 2x 7

697:17x 41

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 7 = 112

Therefore, the value for common factors is 112.

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 = 63868842240/(1x112)

LCM = 63868842240/112

LCM = 570257520

Thus, we can understand that the LCM of 974,840,112,697 is 570257520.
