Given numbers are 624,900,644,138

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

The LCM of 624,900,644,138 is 7534800.

Find LCM of 624,900,644,138 with Prime Factorization

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

2 x 2 x 3 x 23 x 52 x 75 x 7 x 1 = 7534800

Therefore, the lowest common multiple of 624,900,644,138 is 7534800.

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 900 x 644 x 138 = 49910515200

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

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,900,644,138, is 2.

Now, the common factors can be found like this.

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

900:2x 2x 3x 3x 5x 5

644:2x 2x 7x 23

138:2x 3x 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 3x 3x 23 = 3312

Therefore, the value for common factors is 3312.

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 = 49910515200/(2x3312)

LCM = 49910515200/6624

LCM = 7534800

Thus, we can understand that the LCM of 624,900,644,138 is 7534800.
