Given numbers are 920,670,690,286,786

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

The LCM of 920,670,690,286,786 is 3464106360.

Find LCM of 920,670,690,286,786 with Prime Factorization

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

2 x 3 x 5 x 23 x 4 x 67 x 1 x 143 x 131 = 3464106360

Therefore, the lowest common multiple of 920,670,690,286,786 is 3464106360.

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.

920 x 670 x 690 x 286 x 786 = 95609335536000

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

670 : 1, 2, 5, 10, 67, 134, 335, 670

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

286 : 1, 2, 11, 13, 22, 26, 143, 286

786 : 1, 2, 3, 6, 131, 262, 393, 786

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,670,690,286,786, is 2.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

670:2x 5x 67

690:2x 3x 5x 23

286:2x 11x 13

786:2x 3x 131

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 5x 5x 23 = 13800

Therefore, the value for common factors is 13800.

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 = 95609335536000/(2x13800)

LCM = 95609335536000/27600

LCM = 3464106360

Thus, we can understand that the LCM of 920,670,690,286,786 is 3464106360.
