Given numbers are 103,690,129,872

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

The LCM of 103,690,129,872 is 1332420360.

Find LCM of 103,690,129,872 with Prime Factorization

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

2 x 3 x 103 x 115 x 43 x 436 = 1332420360

Therefore, the lowest common multiple of 103,690,129,872 is 1332420360.

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 690 x 129 x 872 = 7994522160

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

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

129 : 1, 3, 43, 129

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,690,129,872, is 1.

Now, the common factors can be found like this.

103:103

690:2x 3x 5x 23

129:3x 43

872:2x 2x 2x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 7994522160/(1x6)

LCM = 7994522160/6

LCM = 1332420360

Thus, we can understand that the LCM of 103,690,129,872 is 1332420360.
