Given numbers are 421,545,109,103

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

The LCM of 421,545,109,103 is 23632835.

Find LCM of 421,545,109,103 with Prime Factorization

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

109 x 421 x 5 x 1 x 103 = 23632835

Therefore, the lowest common multiple of 421,545,109,103 is 23632835.

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.

421 x 545 x 109 x 103 = 2575979015

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.

421 : 1, 421

545 : 1, 5, 109, 545

109 : 1, 109

103 : 1, 103

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,545,109,103, is 1.

Now, the common factors can be found like this.

421:421

545:5x 109

109:109

103:103

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

109 = 109

Therefore, the value for common factors is 109.

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 = 2575979015/(1x109)

LCM = 2575979015/109

LCM = 23632835

Thus, we can understand that the LCM of 421,545,109,103 is 23632835.
