Given numbers are 840,789,802,534,474

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

The LCM of 840,789,802,534,474 is 622868696520.

Find LCM of 840,789,802,534,474 with Prime Factorization

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

2 x 3 x 140 x 263 x 401 x 89 x 79 = 622868696520

Therefore, the lowest common multiple of 840,789,802,534,474 is 622868696520.

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.

840 x 789 x 802 x 534 x 474 = 134539638448320

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.

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

789 : 1, 3, 263, 789

802 : 1, 2, 401, 802

534 : 1, 2, 3, 6, 89, 178, 267, 534

474 : 1, 2, 3, 6, 79, 158, 237, 474

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,789,802,534,474, is 1.

Now, the common factors can be found like this.

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

789:3x 263

802:2x 401

534:2x 3x 89

474:2x 3x 79

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 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 134539638448320/(1x216)

LCM = 134539638448320/216

LCM = 622868696520

Thus, we can understand that the LCM of 840,789,802,534,474 is 622868696520.
