Given numbers are 624,680,861,494,644

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

The LCM of 624,680,861,494,644 is 6652223760.

Find LCM of 624,680,861,494,644 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 13 x 2 x 85 x 41 x 19 x 23 = 6652223760

Therefore, the lowest common multiple of 624,680,861,494,644 is 6652223760.

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.

624 x 680 x 861 x 494 x 644 = 116227653534720

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.

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

861 : 1, 3, 7, 21, 41, 123, 287, 861

494 : 1, 2, 13, 19, 26, 38, 247, 494

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,680,861,494,644, is 1.

Now, the common factors can be found like this.

624:2x 2x 2x 2x 3x 13

680:2x 2x 2x 5x 17

861:3x 7x 41

494:2x 13x 19

644:2x 2x 7x 23

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 2x 2x 2x 3x 7x 13 = 17472

Therefore, the value for common factors is 17472.

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 = 116227653534720/(1x17472)

LCM = 116227653534720/17472

LCM = 6652223760

Thus, we can understand that the LCM of 624,680,861,494,644 is 6652223760.
