Given numbers are 103,987,782,621

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

The LCM of 103,987,782,621 is 715490118.

Find LCM of 103,987,782,621 with Prime Factorization

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

3 x 23 x 103 x 329 x 34 x 9 = 715490118

Therefore, the lowest common multiple of 103,987,782,621 is 715490118.

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.

103 x 987 x 782 x 621 = 49368818142

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.

103 : 1, 103

987 : 1, 3, 7, 21, 47, 141, 329, 987

782 : 1, 2, 17, 23, 34, 46, 391, 782

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,987,782,621, is 1.

Now, the common factors can be found like this.

103:103

987:3x 7x 47

782:2x 17x 23

621:3x 3x 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.

3x 23 = 69

Therefore, the value for common factors is 69.

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 = 49368818142/(1x69)

LCM = 49368818142/69

LCM = 715490118

Thus, we can understand that the LCM of 103,987,782,621 is 715490118.
