Given numbers are 103,170,728,421

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

The LCM of 103,170,728,421 is 2683302440.

Find LCM of 103,170,728,421 with Prime Factorization

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

2 x 103 x 85 x 364 x 421 = 2683302440

Therefore, the lowest common multiple of 103,170,728,421 is 2683302440.

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 170 x 728 x 421 = 5366604880

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

170 : 1, 2, 5, 10, 17, 34, 85, 170

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,170,728,421, is 1.

Now, the common factors can be found like this.

103:103

170:2x 5x 17

728:2x 2x 2x 7x 13

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 5366604880/(1x2)

LCM = 5366604880/2

LCM = 2683302440

Thus, we can understand that the LCM of 103,170,728,421 is 2683302440.
