Given numbers are 840,990,737,626

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

The LCM of 840,990,737,626 is 581316120.

Find LCM of 840,990,737,626 with Prime Factorization

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

2 x 3 x 5 x 11 x 28 x 3 x 67 x 313 = 581316120

Therefore, the lowest common multiple of 840,990,737,626 is 581316120.

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 990 x 737 x 626 = 383668639200

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

737 : 1, 11, 67, 737

626 : 1, 2, 313, 626

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,990,737,626, is 1.

Now, the common factors can be found like this.

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

990:2x 3x 3x 5x 11

737:11x 67

626:2x 313

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 3x 5x 11 = 660

Therefore, the value for common factors is 660.

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 = 383668639200/(1x660)

LCM = 383668639200/660

LCM = 581316120

Thus, we can understand that the LCM of 840,990,737,626 is 581316120.
