Given numbers are 840,746,209,777

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

The LCM of 840,746,209,777 is 2422903560.

Find LCM of 840,746,209,777 with Prime Factorization

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

2 x 3 x 7 x 20 x 373 x 209 x 37 = 2422903560

Therefore, the lowest common multiple of 840,746,209,777 is 2422903560.

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 746 x 209 x 777 = 101761949520

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

746 : 1, 2, 373, 746

209 : 1, 11, 19, 209

777 : 1, 3, 7, 21, 37, 111, 259, 777

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,746,209,777, is 1.

Now, the common factors can be found like this.

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

746:2x 373

209:11x 19

777:3x 7x 37

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

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 101761949520/(1x42)

LCM = 101761949520/42

LCM = 2422903560

Thus, we can understand that the LCM of 840,746,209,777 is 2422903560.
