Given numbers are 903,725,221,169

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

The LCM of 903,725,221,169 is 1880881275.

Find LCM of 903,725,221,169 with Prime Factorization

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

13 x 903 x 725 x 17 x 13 = 1880881275

Therefore, the lowest common multiple of 903,725,221,169 is 1880881275.

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.

903 x 725 x 221 x 169 = 24451456575

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

725 : 1, 5, 25, 29, 145, 725

221 : 1, 13, 17, 221

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,725,221,169, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

725:5x 5x 29

221:13x 17

169:13x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 24451456575/(1x13)

LCM = 24451456575/13

LCM = 1880881275

Thus, we can understand that the LCM of 903,725,221,169 is 1880881275.
