Given numbers are 603,661,421,913,421

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

The LCM of 603,661,421,913,421 is 153204543459.

Find LCM of 603,661,421,913,421 with Prime Factorization

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

421 x 603 x 661 x 1 x 913 x 1 = 153204543459

Therefore, the lowest common multiple of 603,661,421,913,421 is 153204543459.

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.

603 x 661 x 421 x 913 x 421 = 64499112796239

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.

603 : 1, 3, 9, 67, 201, 603

661 : 1, 661

421 : 1, 421

913 : 1, 11, 83, 913

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 603,661,421,913,421, is 1.

Now, the common factors can be found like this.

603:3x 3x 67

661:661

421:421

913:11x 83

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.

421 = 421

Therefore, the value for common factors is 421.

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 = 64499112796239/(1x421)

LCM = 64499112796239/421

LCM = 153204543459

Thus, we can understand that the LCM of 603,661,421,913,421 is 153204543459.
