Given numbers are 840,276,561,739

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

The LCM of 840,276,561,739 is 2669888760.

Find LCM of 840,276,561,739 with Prime Factorization

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

2 x 2 x 3 x 70 x 23 x 187 x 739 = 2669888760

Therefore, the lowest common multiple of 840,276,561,739 is 2669888760.

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 276 x 561 x 739 = 96115995360

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

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

561 : 1, 3, 11, 17, 33, 51, 187, 561

739 : 1, 739

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,276,561,739, is 1.

Now, the common factors can be found like this.

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

276:2x 2x 3x 23

561:3x 11x 17

739:739

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 3 = 36

Therefore, the value for common factors is 36.

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 = 96115995360/(1x36)

LCM = 96115995360/36

LCM = 2669888760

Thus, we can understand that the LCM of 840,276,561,739 is 2669888760.
