Given numbers are 728,426,182,202,121

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

The LCM of 728,426,182,202,121 is 1895037144.

Find LCM of 728,426,182,202,121 with Prime Factorization

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

2 x 7 x 13 x 4 x 213 x 1 x 101 x 121 = 1895037144

Therefore, the lowest common multiple of 728,426,182,202,121 is 1895037144.

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.

728 x 426 x 182 x 202 x 121 = 1379587040832

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.

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

426 : 1, 2, 3, 6, 71, 142, 213, 426

182 : 1, 2, 7, 13, 14, 26, 91, 182

202 : 1, 2, 101, 202

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,426,182,202,121, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

426:2x 3x 71

182:2x 7x 13

202:2x 101

121:11x 11

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 7x 13 = 728

Therefore, the value for common factors is 728.

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 = 1379587040832/(1x728)

LCM = 1379587040832/728

LCM = 1895037144

Thus, we can understand that the LCM of 728,426,182,202,121 is 1895037144.
